阿拉沟水库溢洪道挑流体型结构优化试验研究

Experimental Study on Optimization for Flip Bucket Structure of Alagou Reservoir Spillway

水利枢纽工程经常由于地质条件的原因在工程布置方面受到限制。针对阿拉沟水库溢洪道下泄水流经挑流鼻坎挑射至下游河床及拟人工开挖山体的海漫平台所造成的冲刷和产生的雾化问题,通过多方案的挑流体型结构优化试验研究,获得了适合工程实际的异型挑流鼻坎结构,较好地解决了溢洪道下游消能段的防冲及雾化等问题。

The layout of a hydro project often faces the several limitations resulted from geological conditions. According to the erosion and atomization usually caused by the discharged water flow of Alagou Reservoir spillway flowing through the flip bucket to the downstream riverbed and the mountain apron platform for artificial excavation, the special-shape flip bucket structure suitable for practical engineerings is obtained after several optimization tests and studies for flip figure of bucket, which could better solve the erosion and atomization problems in spillway＇s downstream energy dissipation sec- tion.
