摘要
坝前局部冲刷漏斗形态,是多沙河流上修建的水库设计的主要参数之一,目前多通过模型试验确定.但由于相应的模拟理论尚不完善,造成试验成果与实际情况偏差较大.本文根据坝前水流条件及淤积物特性,导出了粘性淤积物局部冲刷漏斗模型相似准则,并通过模拟某工程实例得到初步验证.
he configuration of scour funnel downstream dams, which is an important design parameter of the reservoirs built on heavily sediment laden rivers, is investigated by the model test. In this paper a model similarity criterion of the scour funnel for cohesive sediment is developed in compliance with the flow conditions and the sediment characteristics downstream dams. A case study for a particular project is given as an example.
