With the rapid development of our national economy, the process of infrastructure construction is also accelerating. China has relatively abundant water resources. In order to make full use of these resources, we must strengthen the construction of water conservancy projects. The quality of water conservancy projects is of great significance to the efficient utilization of water resources. Since the reform and opening up, the construction of water conservancy projects in China has been increasing and numerous water conservancy projects have been built, which has laid a solid foundation for the economic development of China. But what we should see is that a large number of water conservancy projects have quality problems in the process of construction which severely affects their original functions and even causes safety accident. It is not conducive to the development of national economy. Therefore, we should work properly in the quality inspection and control work of water conservancy projects.
  Water conservancy engineering is an important infrastructure for the effective use of water resources. Because most of the water conservancy projects are built in the upper reaches of rivers with relatively complex natural environment, the safety of water conservancy projects has a considerable impact on the safety of people’s lives and property in the lower reaches. Once there are some hidden dangers in the process of construction of water conservancy projects, accidents that may occur after they are put into use will bring huge losses to the people in the lower reaches. This makes the quality inspection and control of water conservancy projects become a very important subject. In the process of project construction, we should always adhere to the policy of “quality first”. In order to adapt to the development of market economy and the requirements of WTO, we should continuously improve the level of quality management and carry out quality inspection and monitoring through tests and experiments so as to find and solve problems in time and then ensure the water conservancy project a high quality.

随着我国国民经济的不断快速发展，基础设施建设的进程也在不断的加快。我国的水利资源相对比较丰富，充分利用这些水利资源必须加强水利工程建设。水利工程的质量的高低对于能否高效的利用水利资源具有十分重要的意义。改革开放以来我国的水利工程建设的力度不断的加大，兴建了大量的水利工程，为我国的经济发展打下了坚实的基础。但是我们应该看到，大量水利工程在建设的过程中存在质量问题，严重的影响了其原本功能的发挥，甚至发生安全事故，不利于国民经济的发展，因此要做好水利工程质量检测与控制工作。
       水利工程是有效利用水利资源的重要的基础设施。由于水利工程大多都是在自然环境相对比较复杂的河流的上游修建，这使得水利工程的安全性对于下游人民的生命和财产安全都有十分重要的影响。一旦水利工程在建设的过程中存在一些隐患，在投入使用之后出现事故就可能给下游的人民带来巨大的损失。这就使得水利工程质量检测与控制成为一个十分重要的课题；在工程施工过程中，要始终坚持“质量第一”的方针，为适应市场经济发展和 WTO 的要求，不断提高质量管理水平，通过试验，检查等进行质量检查、监控，以便及时发现问题，纠正问题，确保实现总体工程质量达到优质工程。

The construction of water conservancy engineering is related to the people’s livelihood and the rapid and healthy development of the national economy. The quality of water conservancy engineering is not only closely related to its own economic benefits, but also related to the safety of people’s lives. The construction management responsibility of water conservancy engineering is considerably weighty. In the process of water conservancy engineering construction in the past, many experiences have proved that only by clearly dividing the construction responsibilities of each participant in the water conservancy projects, strengthening the quality of project management and improving the professional quality of construction personnel can the safety of national property and people’s life and property be ensured. This method can also enhance the reputation and economic benefits of construction enterprises.

  In recent years, China has paid more and more attention to water conservancy engineering and there are more and more new water conservancy projects because of the growing investment. However, the construction management and operation management of water conservancy engineering show a serious imbalance of “separation of management and construction, attaching importance to construction and underrating management”. This requires the organic combination of construction management and operation management of water conservancy engineering and the combination of construction and management to maximize the benefits of water conservancy engineering. Then the modern management of water conservancy engineering can be realized. The management of water conservancy engineering construction is an arduous and complex project. The ultimate goal of construction management is to organize efficient and high-quality management. In the process of project construction, we must reasonably allocate various works, optimize the combination of various production factors, and use modern technology and means to ensure the balance and stability of construction production. By doing these, we can produce more and better qualified engineering products, improve the overall comprehensive benefits of water conservancy engineering enterprises and promote the healthy development of the construction enterprises.

水利工程的建设关系到民生大计和国民经济的快速健康发展，而水利工程的质量也不仅仅只与工程本身的经济效益息息相关，更关系到百姓们的生命安全。水利工程的施工管理责任重于泰山。在过去的水利工程建设过程中，很多经验证明了只有分清楚水利工程各参建方的施工责任，加强工程质量管理，提高施工人员的专业素养，如此才能确保国家财产和人民的生命财产安全无虞，这种做法还能增强企业信誉和企业的经济效益。
       近年来，国家对水利工程越来越重视，投资力度越来越大，新建水利工程项目越来越多，但是水利工程建设管理和运行管理却呈现出“管建分离，重建清管”的严重失调现象。这就需要将水利工程建设管理与运行管理进行有机结合，分实现建管结合，促使水利工程效益得到最大的发挥，进而实现水利工程的现代化管理；水利工程施工项目管理工作是一项艰巨而复杂的工程，组织高效率、高质量的管理是施工项目管理的最终目标。我们在项目施工过程中，必须合理配置各项工作，优化组合各项生产要素，利用现代化的技术和手段，使施工生产的均衡性和稳定性得到保证，以便生产出更多、更好的合格的工程产品，以提高水利工程企业整体的综合效益，促进施工企业的健康发展。

随着社会的发展和科技的进步，建筑设计的水平应不断提高，满足人们的生理及心理需求。市政道桥规划也称城市规划，是城市管理的重要组成部分，是市政建设和管理的依据，也是市政管理中城市规划、城市建设、城市运行三个阶段。本书以实际的市政道桥工程规划设计为载体、以施工过程为主线，注意理论与实际相结合，突出实用性；体现实践运用，其基础内容具有系统性、全面性，具体内容具有针对性、实用性，满足市政道桥工程规划设计与施工需要。

With the continuous acceleration of urbanization construction, the infrastructure constructions is also constantly improving. As a critical part of municipal infrastructure construction, road and bridge engineering has also been greatly developed. Road and bridge construction is a large-scale project, which has a large amount of work and contains various contents. It also has strict requirements for the construction personnel, construction technology, construction safety progress and many other aspects. It is obvious that only by effectively improving the quality of road and bridge construction can the economic interests of construction enterprises be guaranteed and the actual value of road and bridge engineering be brought into full play.
  The scale of cities in China is increasing constantly. At the same time, the number of vehicles and population in the cities are increasing rapidly, which puts forward higher requirements for traffic environment. In order to alleviate the current urban traffic problems, municipal road and bridge engineering is also being carried out successively. The municipal road and bridge engineering has certain complexity. In the construction process, there are a lot of quality factors whose eruption will lead to severe quality problems and even traffic accidents. Therefore, strict management work must be carried out to ensure the quality of the project.
  In order to improve the construction quality of municipal road and bridge engineering in China, the application of municipal road and bridge engineering construction technology has been widely concerned. The application of the technology plays an extremely important role in the construction of municipal roads and bridges. It can not only effectively promote the development of the construction of municipal roads and bridges in China, but also promote the construction of the cities and the development of the whole regional economy in a certain sense.
