With the rapid development of China’s economy, construction has become the most dynamic industry. Throughout the country, tens of thousands of high-rise buildings have sprung up; the rapid development of highway and railway construction has made remarkable achievements; the crisscross road network and railway network continue to extend and improve, effectively promoting the sustained, rapid and healthy growth of the national economy.
    At present, the scale of construction projects is expanding day by day, and the types are increasingly diverse, showing a vigorous development momentum. For the whole construction industry, improving the technical level and professional skills of construction personnel can effectively improve product quality and social benefits. For the construction personnel, improving their professional quality, especially some high-tech operation level, can greatly improve labor production efficiency, reduce labor intensity, speed up project progress, and reduce safety accidents. Therefore, improving the professional and technical level of the majority of construction personnel has become the top priority in the construction industry.
   Construction project safety production work is not only directly related to the safety of people’s lives and property, but also related to the sustained, rapid and healthy development of economic construction, and more importantly, to social stability. How to ensure the safe production of construction projects, avoid or reduce safety accidents, and protect the safety and health of employees, is an important issue in the field of engineering construction. From the perspective of safety accidents in construction projects in China, the root cause of the accidents lies in the lack of knowledge and ability of safety technology and safety management, and the lack of systematic education and training on safety technology and safety management. To this end, the national construction authorities and local authorities have successively promulgated a series of laws, regulations and standards on the safety production management of construction projects, so as to strengthen the safety responsibilities of all parties involved in construction projects, strengthen the supervision and management of construction project safety, and improve the safety level of construction projects in China.

随着我国经济的快速发展， 建设已成为当今最具有活力的一个行业。 纵观全国，数以万计的高楼拔地而起；公路、铁路建设发展迅猛，成就斐然，纵横交错的公路网和铁路网不断延伸、完善，有力地推动着国民经济持续快速健康增长。
       当前，建设工程的规模日益扩大，种类日益繁多，呈现出蓬勃发展的势头。对于整个建设行业来说，提高施工人员的技术水平和专业技能，可以有效地提高产品质量和社会效益。对于施工人员来说，提高自身的专业素质，特别是一些高技术含量的操作水平，可以大大提升劳动生产效率、降低劳动强度、加快工程进度、减少安全事故。因此，提高广大施工人员的专业技术水平，已成为当今建设行业的重中之重。
       建设工程安全生产工作不仅直接关系到人民群众生命和财产安全，而且关系到经济建设持续、快速、健康发展，更关系到社会的稳定。如何保证建设工程安全生产，避免或减少安全事故，保护从业人员的安全和健康，是工程建设领域急需解决的重要课题。从我国建设工程生产安全事故来看，事故的根源在于广大从业人员缺乏安全技术与安全管理的知识和能力，未进行系统的安全技术与安全管理教育和培训。为此，国家建设主管部门和地方先后颁布了一系列建设工程安全生产管理的法律、法规和规范标准，以加强建设工程参与各方的安全责任，强化建设工程安全生产监督管理，提高我国建设工程安全水平。

Water is the basic natural resources and strategic economic resources. The sustainable utilization of water resources is an important guarantee for the sustainable development of economy and society. China is one of the countries with the poorest per capita water resources in the world due to the serious shortage of fresh water resources and extremely unbalanced spatial and temporal distribution. With the rapid development of economy and society and the continuous growth of population, the contradiction between supply and demand of water resources has become increasingly prominent, which has become an important constraint factor for the sustainable development of China’s economy and society.
    At present, China’s water conservancy work has entered a new period. The Party Central Committee and the State Council attach great importance to water conservancy work, regard water resources as an important strategic resource, and emphasize the sustainable utilization of water resources to support the sustainable development of society. With the deepening of the social understanding of the important position and role of water conservancy, especially the new ideas of water control proposed by the Ministry of Water Resources, water conservancy will usher in a new period of rapid development, and water conservancy infrastructure has a long way to go.
    This paper mainly introduces the main technology of water conservancy construction, as well as the management and supervision of each link in the construction process, so as to better promote the smooth construction and completion of water conservancy projects. Doing a good job in all aspects of planning and design of water conservancy projects and in risk assessment, timely supervising the progress of the whole project, doing a good job
in technical training for construction personnel, and improving the overall quality of construction workers can promote the development and progress of water conservancy project construction and lay a good foundation for the national economic development and social progress.
     In the process of writing, this book has referred to and learned from the relevant theories and research of domestic and foreign scholars, and I would like to thank you very much. Due to the lack of time, it is inevitable that there are some deficiencies in the book. Please put forward your valuable suggestions for amendment.
