三峡工程规划与综合利用

三峡水利枢纽工程是治理开发长江的关键性工程,承担着防洪、发电、航运等综合利用任务。工程建成后可确保荆江地区防洪标准不低于百年一遇,大大缓解长江中下游防洪压力,为经济建设发展迅速的华中、华东、华南地区提供巨大的能源支持,从根本上改善川江航运条件,同时枯季补偿调节可提高长江中游河段航道水深和改善航运条件。新时期,长江治理、开发与保护对三峡工程运行提出了新要求,如何优化水资源利用,实施科学调度,全面提升水库综合效益,是三峡工程今后面临的一项长期任务。     

The resettlement planning and practice of Three Gorges Project

Migrant resettlement is essential to the success of the Three Gorges Project (TGP),and the smooth implementation of resettlement is ensured by the resettlement planning and effective organization management.In the process of resettlement planning and implementation,systematic legislation and document support system is established;environmental capacity analysis and assets appraisal methods are introduced;resettlement sites are selected through in-depth analysis and comparison;the relationship between resettlement compensation and local development is correctly understood and considered,and reasonable resettlement schedules are well prepared.Through the establishment of efficient management system and capital management mode of "static control and dynamic management",as well as the timely adjustment of plan according to actual situations,the resettlement is accomplished smoothly.Thus,the social stability of the reservoir area is ensured;the economic development of reservoir area is promoted,and it has promoted successfully the improvement of legislation,regulations and techniques for land requisition and resettlement.The paper also discusses the theory and prospective work of resettlement.     

The design of Three Gorges Hydropower Station

Using physical model and numerical simulation techniques,some technical problems were studied systematically,including layout of power station,measures of sediment and floating debris discharging,types of intake,embedded types of spiral case,layout of underground powerhouse tunnel group and block reinforcement.It was optimal in technique and economy with the arrangement of powerhouse at the dam-toe of both banks +underground powerhouse in the right bank,as well as the intake with a single and small orifice.The sediment and debris problems could be solved with disperse sediment ejection and floating debris discharging holes.With the adoption of techniques for spiral cases such as heat and pressure preservation,cushion layer and combined embedding,the stable operation of generating units can be guaranteed.The arrangement of tailrace tunnel with sloping ceiling was better than that of tailrace surge tank.The technical requirements related to the embedding type of spiral case were proposed.The reinforcement of huge unfavorable blocks was discussed and the new idea for block reinforcement using anti-sliding piles and normal compressive stress of structural plane was put forward.
