1 概况为研究盘石头水库二期汛期堆石坝坝体和上下游围堰的稳定性,以及泄流能力、流速、水深、压力等有关水力学参数,优化比选过流保护方案及措施,采用模型比尺λ_L=36的正态动床水工模型进行混凝土面板堆石坝及土石围堰过流的试验研究。试验过坝流量为2340、1241、405m~3/s,相应上游水位为199.38、198.20和197.04m。2 模型范围及模拟
1 Overview In order to study the stability of the dam body and upstream and downstream cofferdams of the second phase flood season in Panshitou Reservoir and the hydraulics parameters such as discharge capacity, velocity, water depth and pressure, optimize the overcurrent protection scheme and measures, The experimental study on the overcurrent of concrete face rockfill dam and earth rock cofferdam using normal movable bed hydraulic model of model scale λ_L = 36. The tested dam flow rate is 2340,1241,405m ~ 3 / s, the corresponding upstream water level is 199.38, 198.20 and 197.04m. 2 model range and simulation
