摘要
为了改善溢洪道下游消力池的流态和减轻下游的冲刷,采用物理水工模型试验,对光滑溢洪道及不同高度阶梯溢洪道的水力特性进行了试验研究。研究结果表明,采用阶梯溢洪道之后,能大大提高溢洪道的消能率,减小消力池的入水速度,有利于下游河道及滑坡体的稳定。模型试验成果为工程中溢洪道的优化设计提供科学依据。
In order to improve the flow pattern duce downstream erosion, of the different height of s of the stilling basin in the downstream greatly improve the energy dissipation rate, reduce the speed ducive to tile stability of the downstream rivers and landslides. for the optimization of spillway in the project design. of the spillway, and rehydraulic characteristics the stepped spillway can of water into the stilling basin, which is conThe model test results provide a scientific basis
