水利工程建设项目的前期工作包括项目建议书、可行性研究阶段、初步设计阶段和工程招标阶段。项目建议书是在流域规划的基础上,由主管部门提出的工程项目轮廓设想,主要衡量分析工程项目建设的必要性和可行性,可行性研究是运用现代生产技术科学、经济学和管理学对建设项目进行技术经济的综合分析。初步设计时充分利用水资源,贯彻综合利用、就地取材原则,对项目的技术经济标准等指标进行论证,并进行方案比较。 The preliminary work of the water conservancy construction project includes project proposal, feasibility study stage, preliminary design stage and project bidding stage. The project proposal is based on the river basin planning and the proposal of the outline of the project project proposed by the competent department. It mainly analyzes the necessity and feasibility of the analysis of the project construction. The feasibility study is based on the use of modern production technology science, economics and management. The construction project carries out a comprehensive analysis of technology and economy. In the initial design, we will make full use of water resources, implement the principles of comprehensive utilization and local materials, demonstrate the technical and economic standards of the project, and compare the plans.
