摘　　要：通过建立了三里坪水电工程整体水工物理模型,对泄洪洞出口挑流鼻坎的型式进行了多方案对比优化试验,试验结果表明,优化后的挑流出口型式可使得出流充分消能,且无论在高水头或低水头时均无溅击建筑物所在岸边的现象发生,可保证泄水建筑物的安全,并作为工程设计的科学依据。In the Sanliping hydropower project integer hydraulic physical model ,many kinds of optimum design for the flip bucket pattern of flood- releasing tunnel outlet are compared , and the conclusions are as follow. energy dissipation of outflow nappe is sufficient after optimum, scouring of the nearer bank doesn＇t occur both at high water level and at low water level. That ensure security of flood-releasing structure. According to the project fact, it can be the scientific foundation of the project design.
