In the network society, information resources are the basic elements of productivity. As a strategic resource, information resources play an important role in economic construction and social development. The library is one of the main distribution centers for information resources and an important part of the information industry. It should adapt to the impact of new technology applications and changes in social information needs, and develop information resources in depth. By reorganizing and collating information resources to provide high-level, high-quality, high-intelligence and diversified information products, libraries should become the resources needed by specific users to meet the diversified and multi-level needs of information resources for social development. This has been the responsibility of contemporary library managers.

Information is the main strategic resource and valuable asset of the network society. In the fierce international competition, information resources have become the focus of competition among countries, and it is the embodiment of international competitive advantage. The development and construction of information resources has become an important driving force for social and economic development. Compared with developed countries, China's information resource development and utilization level is still very low, about 2~3 orders of magnitude lower. Compared with the actual needs of Chinese users, there are still many gaps and problems to be solved.

在网络社会中，信息资源是生产力的基本要素，信息资源作为一种战略性资源，在经济建设与社会发展中起到举足轻重的作用。图书馆是信息资源的主要集散地之一，是信息产业的重要组成部分。如何适应新技术应用及社会信息需求变化带来的影响，深层次的开发信息资源，通过对信息资源的重组、整理，提供高水平、高质量、高智能含量并且多元化的信息产品，使之成为特定用户需要的资源，以满足各个阶段、各个层次、众多领域社会发展对信息资源多元化、多层次需求，已经当代图书馆管理人员责无旁贷的使命。

信息是网络社会的主要战略资源和宝贵财富，在激烈的国际竞争中，信息资源成为各国争夺的重点，是国际竞争优势的体现。信息资源开发与建设已经成为社会经济发展的重要推动力。我国的信息资源开发与利用水平与发达国家相比还很低，约低2～3个数量级；与我国用户需求的实际需要相比，还有很多差距，存在诸多亟待解决问题。

Water resources are an important material basis for maintaining human survival and promoting social development. The development and utilization of water resources is an aspect of transforming and utilizing nature. With the rapid development of China's economy, water shortages and water pollution have become increasingly serious. Therefore, it is particularly important to strengthen the rational development and sustainable use of water resources. At the same time, the development of economy and science and technology also makes the water conservancy enterprise in the lifeblood of the national economy and the position of the basic industry more prominent. The improvement of water conservancy construction is of great significance to further promote the development and utilization of hydropower, protect the ecological environment and promote China's economic development.

This book first introduces the status quo and problems of water resources development and water conservancy project construction. The next six chapters are the foundation for water resources development, water resources development and utilization, water resources development and utilization projects, water conservancy projects, water conservancy and hydropower projects, and construction management of engineering projects. They elaborate the theory, technology and construction of water resources development.

As the book contains more content, involves more cumbersome knowledge, and has more compilers, the format, depth and breadth of the contents of each chapter may not be inconsistent; and the fallacies are inevitable. Readers are invited to criticize and correct. Suggestions for improvement will be gratefully received.

本书开篇对水资源开发与水利工程建设的现状与问题进行概述，后又分为水资源开发基础、水资源开发利用、水资源开发利用工程、水利工程建设、水利水电工程建设与工程项目的施工管理六章分别对水资源开发的理论、技术与水利工程施工建设进行详细阐述。

由于本书包罗内容较宽泛，涉及知识较烦琐，编写人员较多，各章节内容的格式、广度和深度可能并不一致，且谬误无可避免，敬请读者批评指正。

Hydrogeology refers to the changes and movements of groundwater in nature. Hydrogeology is the science of studying groundwater. It is a branch of geology, which mainly studies the distribution and formation of groundwater, the physical properties and chemical composition of groundwater, groundwater resources and their rational utilization, the adverse effects of groundwater on engineering construction and mining and their prevention and control. With the development of science and the needs of production and construction, hydrogeology is divided into regional hydrogeology, groundwater dynamics, hydro geochemistry, water supply hydrogeology, mine hydrgeology, soil improvement hydrogeology and other sub-disciplines.

Rational development and utilization of water resources is the embodiment of the concept of sustainable development in water resources. While taking into account social economy and environmental protection, water resources are effectively exploited. In addition, this activity can be continued.

This book was divided into 12 chapters to analyze and elaborate hydrogeology and water resources development. We hope it will help some of the relevant staff.

水文地质，指自然界中地下水的各种变化和运动的现象。水文地质学是研究地下水的科学，它是地质学的一个分支学科，主要是研究地下水的分布和形成规律，地下水的物理性质和化学成分，地下水资源及其合理利用，地下水对工程建设和矿山开采的不利影响及其防治等。随着科学的发展和生产建设的需要，水文地质学又分为区域水文地质学、地下水动力学、水文地球化学、供水水文地质学、矿床水文地质学、土壤改良水文地质学等分支学科。近年来，水文地质学与地热、地震、环境地质等方面的研究相互渗透，又形成了若干新领域。

水资源合理开发利用是人类可持续发展概念在水资源问题上的体现。是指在兼顾社会经济需水要求和环境保护的同时，充分有效地开发利用水资源，并能使这种活动得以持续进行。

本书分十二章内容对水文地质与水资源开发进行相应的分析与阐述，希望能够帮助一些相关工作人员。

As the most critical part of the whole process of engineering construction projects, water conservancy project design determines the key to the success of the project. The core of water conservancy project design quality management is to establish a set of systematic project management system, so that the design unit can solve the problems existing in project design stage between the owner, the government construction related departments and other relevant units or institutions involved in the project construction. In the design of water conservancy projects, only the combination of professional design and project cost preparation can ensure that the designed project results are scientific, reasonable and economically feasible. With the rapid development of the social economy, China's water conservancy industry has made great progress. The quality of water conservancy projects directly affects the normal life of the surrounding residents. The concrete construction of water conservancy projects needs to be carried out according to the engineering design. Therefore, the scientific design will inevitably affect the quality of the project, so the construction personnel must constantly improve the design of water conservancy projects to further control the occurrence of safety hazards. The book mainly analyzes the necessity of improving the current water conservancy project design, and proposes corresponding improvement measures according to the existing deficiencies, hoping to provide relevant reference to relevant people.

Any project needs to go through the design stage before construction to provide a reference for the construction of the project, as well as in water conservancy projects. Before the construction, the design unit will go to the construction site to conduct detailed investigation and understanding of the geological and hydrological conditions, climatic conditions and the surrounding environment, and then make a design plan based on the actual points of the project. In the design process, for which problems need to be paid attention to in the construction process, the process arrangement of each construction stage, the construction progress of the project, and various cost and expenditure will be clearly marked. If the actual construction estimation is insufficient at a certain stage, it will affect the quality of the construction, and then there will be changes in the cost and expenditure, which will seriously affect the smooth progress of the construction.

水利工程设计作为工程建设项目整个过程中最为关键的环节，决定着项目工程的实施成败的关键。水利工程设计质量管理的核心是通过建立一整套的系统化项目管理制度，以利于设计单位在业主、政府建设相关的主管部门及其他参与项目建设的相关单位或机构之间解决项目在设计阶段中存在的问题。在水利工程项目设计中，只有各专业设计与项目造价编制有机的结合，才能确保设计出来的项目成果科学合理、经济可行。伴随着社会经济的快速发展，我国水利事业得到很大进步。水利工程建设的好坏直接影响到周边居民的正常生活。具体的水利工程施工需要根据工程设计来进行，所以，设计的科学与否必然会影响到工程的质量，所以施工人员必须不断完善水利工程设计，进一步控制安全隐患的发生。本书主要通过对当前完善水利工程设计的必要性进行分析，并根据其中存在的不足提出相应的完善措施，希望能够给相关人士提供一定的借鉴性。

任何一项工程在施工之前都需要经过设计阶段，为工程的施工提供参考依据，在水利工程中同样如此。在施工之前，设计单位会到施工现场，对地质水文状况，气候条件以及周围环境等进行详细的调查了解，然后结合工程的实际点，作出设计方案。在设计的过程中，对于在哪个施工环节需要注意哪些问题，各个施工阶段的工序安排，工程的施工进度，以及各项成本支出都会作出明确的标示。如果在某一阶段对实际施工估算不足，就会影响到施工的质量，进而在成本支出方面出现变动，严重影响到施工的顺利进行。

As an important construction project connecting different regions, roads and bridges have an important impact on China’s economic development and cultural exchanges. As the saying goes: “To be rich, build roads first”. With a developed transportation system, it is possible to achieve better economic and cultural development in China’s vast territory. Therefore, the importance of municipal roads and bridges engineering is obvious, and the current quality requirements for roads and bridges are becoming stricter.

Over the years, with the development of urbanization, the quality of municipal road construction and water supply & drainage project has been greatly improved; while the urban transportation system has been continuously improved. Compared with the backward transportation system in the past, it has fundamentally improved and achieved leap-forward development. However, a series of municipal engineering problems were also reflected in those "crisp buildings" reported by various news sources a few years ago and various shoddy projects for now. 

First of all, the construction quality supervision system is imperfect, and the management loopholes are large. Some government officials abuse their power, draw illegal interests from the construction of the project, and cut corners. The quality of construction is difficult to guarantee. Secondly, the level of construction technology is not high. Many technical problems cannot be fundamentally solved, but only traditional construction methods are used. Finally, due to the neglect of the maintenance work of the bridge, a series of quality problems such as collapse of the bridge and delamination of the pavement have occurred. There’s huge potential safety hazard. 

Therefore, this book is divided into three parts to elaborate and analyze the municipal roads & bridges and water supply & drainage projects, hoping to promote the development of China’s municipal engineering construction.

道路桥梁作为连通不同地区的重要建设工程，对我国的经济发展以及文化交流都有着重要影响。俗话说：要想富，先修路。有了发达的交通方式，才有可能在我国辽阔的地域中取得更好的经济文化发展。因此，市政道路桥梁工程的重要程度可见一斑，并且当前对道路桥梁的质量要求愈发严格。

这些年来，随着城市化的发展，市政道路建设和给水排水工程质量有了很大的提高，城市交通体系也不断地完善。与以往落后的交通体系相比，从根本上得到了很大的改善，实现了飞跃地发展。但由几年前被各界新闻媒体报道的“楼脆脆”，到现在的各种豆腐渣工程的桥梁等，也都折射出一系列的建设工程问题。

首先，施工的质量监督体系不完善，管理漏洞大，一些政府官员滥用职权，从工程建设中牟取不法利益，偷工减料，施工的质量得不到保证。其次，施工技术水平不高，很多技术性问题无法从根本上得到解决，而仅仅是使用传统的建筑方法。最后，由于疏忽了对桥梁的维护工作，造成了桥梁塌陷，铺层脱落等一系列的严重问题，存在着巨大的安全隐患。

因此，本书分三部分对市政道路桥梁与给排水工程进行详细的阐述与分析，希望对我国市政工程建设事业的发展有一定的推动作用。
