摘要
基于巴基斯坦Darawat大坝的泄洪消能的水工模型实验,在不同工况下,观测溢流坝挑流跌流过程,并测量了溢流坝下游冲坑地形。分析实验数据,发现坝址左岸坡基岩出露,需对右岸岸坡进行防护。实验结果证明:增大宽尾墩的折角可实现对本方案的优化,设计方案布局合理。该结论为有效解决同类实际工程问题提供了一种新的方法。
A study is made based on the hydraulic model test of the Pakistani Darawat Dam under different test conditions. Observa- tion of the trajectory flow and overfall flow of the spillway and measurement of the scouring topography of the spillway downstream have been accomplished. It is found that bedrock on the left bank of dam site is exposed on the basis of the test data. It is necessary to take effective engineering measures to protect the right bank slopes. The test has proved that using the way of enlarging the bevel of flaring pier can optimize project design. The overall arrangement of the dam is rational. This conclusion serves as a scientific way to solve the practical problem of the same type of project.
