汾河二库大坝建成后,水库在泄洪时水力边界条件发生了巨大变化,泄洪冲刷对大坝及附近建筑物是否安全显得十分重要。选取坝脚至电站防洪堤一段进行动床水工模型试验研究,主要对大坝底孔和大坝表孔在各种运行工况下的试验研究结果进行了详述,并对大坝及附近建筑物受泄洪冲刷的影响进行评价。 After the completion of the Fenhe Second Reservoir Dam, the hydraulic boundary conditions of the reservoir have undergone tremendous changes during flood discharge. It is very important that the flood discharge scour is safe for the dam and nearby buildings. Select dam section to the first section of the flood control embankment for dynamic bed hydraulic model test research, mainly on the bottom of the dam and the dam hole in a variety of operating conditions of the experimental study carried out in detail, and the dam and nearby Buildings are evaluated for the impact of flood scouring.
