摘要
根据斗槽式取水构筑物室内模型试验结果,对全断面斗槽和设置分流墙后的水力冲沙特性进行了理论分析,说明在斗槽下游冲沙最不利流段设置分流墙后,分流段的流速要比全断面同流段流速提高一倍。分流冲沙是解决斗槽水力清淤的一种有效方法。
Based on the results of model test, the hydraulic characteristic of sluicing sand with shunt wall built and without have been analyzed. The flow velocity is doubled when shunt wall is built in the low velocity zone. Shunt wall built in diversion flume is an effective method to clear silt by hydraulic energy.
