摘要
某混凝土重力坝位于热带雨林地区,最大坝高156 m。坝址河谷狭窄,河道纵坡较陡,坝后地质条件较差,消能防冲设计难度大。经设计分析及模型试验,确定采用宽尾墩加台阶加挑流联合消能方式,取得了良好的效果。
A concrete gravity dam is located in a narrow valley with steep longitudinal slope in the tropical rain forest. Its maximum dam height is 156 m. The geologic condition behind the dam is poor and the design of energy dissipater is difficult greatly. Through the design analysis and model test, the way wide flange pier with step is adopted and the method deflecting flow is combined, which could obtain good results.
