| 摘 要： | 龙开口水电站坝址处河床窄、泄洪频率高、流量大,是典型的大单宽流量高混凝土坝,此类工程对泄水建筑物的消能防冲效果和运行安全性都有很高的要求.以水工模型优化试验为手段,通过对各典型工况消能防冲效果以及流态的研究,得出宽尾墩挑流方案的不足之处,同时探讨并论证了大差动-舌形坎挑流方案的优越性.研究成果对同类型工程枢纽的消能防冲设计有一定的借鉴意义.

| Abstract: | The dam site of Lonkaikou hydropower station is located at a narrow valley,and the flood discharge is large and frequent.This project is the typical high concrete gravity dam with large unit width discharge.The energy dissipation and erosion prevention effect and the operation security is highly demanded of such project.By the optimal hydraulic model test,this article concludes the shortcoming of flaring-tail pier and deflecting flow scheme through the study of energy dissipation and erosion prevention effe... |
