摘要
根据不同堰型对比分析,堰流的流量系数变化,主要受堰边界条件的影响。故在多沙河流的模拟试验或水工建筑物设计中,应充分考虑泥沙因素,采取有效措施,使堰前不发生淤积,消除"再生"边界条件对过流能力的影响。
According to comparative analysis of different weirs, the discharge coefficient of weirs is mainly affected by changes in the boundary conditions of the weirs. Therefore,the hydraulic simulation tests or the design of water projects in the sediment-- laden river should take fully into account of sediment factors and take effective measures to make deposit never occur before the weirs and eliminate the impact of boundary conditions on the capacity of the flow.
