| 摘 要： | 通过新疆红山嘴电厂五级电站压力前池的水力学模型试验。观测了电站甩负荷后压力前池流场的水位、流速分布、各建筑物的分流比、水流流态及输排沙的基本特性。分析了甩负荷后压力前池的水流流态优于正常运行时的原因。验证了三角形导沙坡设计的可行性。为解决压力前池内特殊条件下的输排沙提供了一种新型导沙装置。

| Abstract: | Through the hydraulic model experiment of Hongshanzui fifth-class hydropower station's pressure forebay in Xinjiang, the water level, velocity distribution, diversion ratio of each construction, flow pattern and sediment transport characteristics of pressure forebay after the load rejection were observed in this experiment, as well as the reason of flow pattern was analyzed which occurred after the load rejection and was better than that which occurred and was normal operation. The experiment also verified the feasibility of triangular bed load deflecting slope, and provided a new sediment guiding equipment to pressure forebay under the special conditions. |
