Engineering construction and technology is an important part of the construction project objectives of the highway construction industry. The realization of reliable construction quality, efficient efficiency and personal safety of participants is not only related to the construction environment of the project, but also to the management mode of the construction project. However, in China’s highway construction industry, the current situation and management effect of construction technology management are not optimistic, the construction efficiency is low, the progress is slow, and the waste of personnel and property is serious. The main reason for this phenomenon is that the construction and technical management are not comprehensive enough and standardized management is not carried out, which makes some management not well implemented.
        The technical operation process and operation specifications in the construction process are closely related to the quality of the project and the safety of the construction personnel. Although our country has begun to attach importance to the construction of construction site construction operation management system, and initially established the corresponding construction manual and management system, but these manual and system are not well implemented in the actual construction process due to various reasons, resulting in the reduction of construction management role and construction management confusion. And it has a negative impact on the survival of enterprises and the overall development of highway engineering construction industry.
     Therefore, this book analyzes the contemporary highway engineering construction and technology from nine chapters, and analyzes the reasons for the current situation of highway engineering construction in China, so as to ensure the smooth progress of highway construction in China.

工程施工及技术是公路建设行业施工项目目标的重要组成部分。可靠的施工质量、高效的效率和参与人员人身安全的目标实现，不仅与项目施工环境有关，也和施工项目的管理方式有关。然而，在我国公路建设施工行业里，施工技术管理现状及管理效果不容乐观，施工效率低、进度慢，人员和财产浪费比较严重。造成这种现象的主要原因在于施工及技术管理不够全面，没有进行标准化管理，从而使得某些管理没有得到很好的落实。
        施工过程中的技术操作流程、操作规范与工程项目的质量及施工人员的安全息息相关。虽然我国已经开始重视施工现场施工操作管理体系的建设，也初步建立了相应的施工手册和管理体系，但是这些手册和体系在实际的施工过程中由于各种原因没有很好地执行，导致施工管理作用降低和施工管理的混乱，对企业的生存和公路工程施工行业的整体发展产生负面影响。
        因此，本书从九章内容对当代的公路工程施工与技术进行分析，对我国公路工程施工现状进行原因剖析，以保证我国公路建设事业的顺利进行。

Highway transportation has become an important part of modern comprehensive transportation system because of its flexibility, rapidity, convenience, mobility, wide coverage, deep access and good accessibility. It is an important basic industry of national economy and a new economic “growth point”, is the lifeline of rapid, healthy and sustainable development of society and economy, and to a certain extent marks the level of social and economic development of a country or region. Since the Reform and Opening up, in order to meet the needs of social and economic development, China’s highway transportation has entered a new development period. The mileage, volume of road transportation and the number of civil vehicles have increased substantially, and the trunk road network covering the whole country and provinces has gradually formed. The highway construction project can not be completed on time without effective and reasonable management. Only by paying attention to the management role of highway engineering projects, can we minimize the errors in the process of highway construction and improve the quality of highway construction. Highway engineering management is a complex system work. Different engineering projects have different management measures. Therefore, highway engineering managers should not only follow the systematic and scientific engineering management methods, but also keep pace with the times, boldly seek new things, strengthen highway engineering management, strictly control all aspects of construction, and take measures in advance to ensure the smooth progress of highway engineering; at the same time, the managers also need to summarize the experience and lessons in the highway engineering, in-depth study of highway engineering management methods, improve the highway engineering construction process, so as to improve the efficiency of highway engineering construction and promote the rapid development of Highway Engineering in China.
    Combined with the practical work experience of highway engineering management, this book systematically summarizes and discusses the theoretical knowledge of highway engineering management, as the theoretical guidance of highway construction management in the future, and enriches the literature of highway engineering management.

公路交通以其灵活、快捷、方便、机动、覆盖面广、通达深度深、可达性好等特点，成为现代综合交通运输体系的重要组成部分。它是国民经济的重要基础产业和新的经济“增长点”，是社会及经济快速、健康、持续发展的生命线，并在一定程度上标志着一个国家或地区社会经济的发展水平。改革开放以来，为了适应社会经济发展的需要，我国公路运输进入了一个新的发展时期，公路里程、公路运输量和民用汽车保有量均大幅度增长，覆盖全国及各省的干线公路网己逐渐形成。公路建设项目如期完成离不开有效合理管理，只有注重公路工程项目的管理作用，才能最大限度地减少公路建设过程中的失误，提高公路建设质量。公路工程管理是一项复杂的系统工作，不同的工程项目，所采取的管理措施存在差异，因此，公路工程管理者不仅要遵循系统、科学的工程管理办法，而且要与时俱进，大胆求新，加强公路工程管理工作，对施工中各个方面严加控制，提前做好应对措施，保证公路工程顺利进行；同时，管理者还需要在公路工程中总结经验教训，深入研究公路工程管理方法，完善公路工程施工过程，从而提升公路工程施工效率，促进我国公路工程的快速发展。
       本书结合公路工程管理方面的实际工作经验，系统归纳与论述了公路工程管理理论知识，作为今后公路建设管理的理论指导，同时丰富公路工程管理方面的文献资料。

In the field of microbiology, the development of molecular biology, moleculargenetics and ecology has promoted the development of environmental microbiology.Many microbial application technologies have penetrated into the environmentalprotection work, and played an important role in improving human living environmentand eliminating environmental pollution. Microorganism is the basic component of natural ecosystem, which is closely connected with material circulation and energy flow. It decomposes all kinds of organic matters in the environment, including all kinds of wastes and organic pollutants generated by human activities, maintains the relative balance of natural ecosystem while maintaining its growth and reproduction, and helps human beings“clean” the environment.

Environmental microbiology is a professional basic course for environmentalprotection majors. It provides students with the necessary basic theories and experimentalskills of microorganisms for learning water pollution control engineering, air pollutioncontrol engineering, environmental monitoring, solid waste treatment and utilization andother professional courses. Higher vocational colleges train high skilled applied talents tomeet the needs of production, service and management. For this purpose, the compilationof this textbook systematically introduces the basic knowledge of microbial morphology,structure, nutrition, metabolism, growth and reproduction, and genetic variation in accordance with the principles of “theoretical teaching sufficiency” and “practice,practicality and practice”. On the basis of meeting the needs of subsequent courses, some contents are adjusted and deleted. For example, the metabolism of microorganisms is only introduced the metabolism of production capacity. In the practical application of microorganisms, the influence of microorganisms on the environment, the role of
microorganisms in the natural material circulation, and the application of microbial technology in environmental management are introduced. The experimental part includes the basic skills and operation methods of microorganisms, the detection of microorganisms in water and air, the separation, screening and cultivation of high efficient pollutant degradation strains.

Due to the limited level of editors, it is difficult to avoid the mistakes or omissions in the book. We sincerely ask our colleagues and readers to criticize and correct them.
