三峡工程电站设计
利用物理模型和数值模拟技术，系统研究了三峡电站布置、排沙及排漂措施、进水口形式、机组蜗壳埋设方式，以及地下电站洞室群布置、块体加固等技术问题。研究表明，三峡电站采用两岸坝后厂房＋右岸地下厂房的布置及单孔小孔口进水口体型技术经济最优，采用分散排沙和排漂孔可较好解决电站的泥沙和漂污问题，蜗壳采用保温保压、垫层及组合埋设技术均可保证机组稳定运行，采用新型变顶高尾水洞优于设置尾水调压室。同时提出了与蜗壳埋设方式相关的技术标准，并对大型不利块体的加固进行了探讨，提出了利用阻滑键及结构面法向压应力加固块体的新思路。...

| Notes | 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 case 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 rein |
