糯扎渡水电站调压室优化设计及应用

Optimum Design and Application of Surge Chamber of Nuozhadu Hydropower Station

糯扎渡水电站调压室规模巨大,为适当控制地下洞室开挖规模,降低施工难度,介绍通过水力过渡过程数值分析和模型试验优化调压室体型,论证了合理利用导流洞减小调压室断面尺寸的可行性,实践运行证明调压室优化设计是合理可靠的,并获得较好的应用价值。

The surge chamber of Nuozhadu hydropower station has a huge scale. In order to control the excavation scale of underground cavern and reduce the construction difficulty, numerical analysis of hydraulic transition process and model test are introduced to optimize the shape of surge chamber. The feasibility of using diversion tunnel reasonably to reduce the section size of surge chamber is demonstrated. Practical operation proves that the optimization design of surge chamber is reasonable and reliable, and has obtained better application value.
