摘要
针对杂木寺水电站枢纽布置、泄水建筑物进口及消能工的体型优化、库区拉沙以及下游河道的消能防冲等问题进行了41个方案的试验研究和论证分析,通过在电站进口加设导沙坎、在泄洪冲沙闸末端加设小挑坎以及在消力池右边墙出口段加设导流墩等措施,较好地解决了库区拉沙问题及枢纽的泄洪消能问题。提出的推荐方案具有体型简单,易于施工,操作灵活、工程量小、下游河道冲刷较浅等优点,达到了泄洪消能试验的目的,满足了设计要求,并被应用于工程设计中。
In view of Zhamusi project structure arrangement, shape optimization of release structure inlet and dissipator, as well as reservoir sediment discharge and energy dissipation and erosion control of downstream channel, tests and analysis are made on 41 alternatives. By adding a silt an＇ester at the intake and a small flip bucket at the end of the flood discharging and sand sluicing gate or adding a diversion pier at the outlet section of the right wall of stilling basin, the issue of reservoir sediment discharge and structure energy dissipation is well solved. The proposed alternative, with the advantages of simple shape, easy construction, flexible operation, small work quantity and shallow erosion in downstream channel, has reached the objectives of flood discharging and energy dissipation tests, met the design requirements and been applied in project design.
