寺沟峡水电站下游水力特性研究分析

Study and Analyses of Downstream Hydraulic Characteristics of Sigouxia Power Station

寺沟峡水电站是目前待建的“一机一孔”的新型水电站，通过水工模型试验，对枢纽下游水力特性进行研究，具体描述了下游的三种不同流态的运动规律、两种典型工况下游流速的沿程分布及三种不同冲刷形态的形成原因，探讨了各种因素对下游河床冲刷的影响。

Sigouxia is a new type power station with ＇one machine one hole＇, which is to be built. The downstream hydraulic characteristics of the project were studied by means of hydraulic model test. The movement rules of three kinds of flow regime under two different conditions, the distribution of the velocity of flow on two specific circumstance and the three different erode forming reasons of shape were described concretely, and were probed into the influence that various kinds of factors erode to the downstream riverbed separately.
