摘　　要：为了保证汉江蜀河水电站截流工程成功实施,进行了截流水工模型试验研究。针对蜀河水电站设计中用于导流的泄洪闸高于原河床3.5m的实际情况及设计截流流量大的特点,通过不同设计截流流量方案的试验研究,获得了截流过程龙口的系列水流要素,确定了不同龙口宽度时抛投材料的粒径和抛投强度,推荐采用单戗单向截流的方案,为工程截流的实施提供了科学依据。In order to guarantee the success of work for river closure of Shuhe River hydropower station project in Hanjiang River,the hydraulic model test of river closure was carried out.According to the characteristics of the Shuhe River Hydropower Sluice being 3.5m higher than the original river bed and large flow of design closure being larger than normal,through the different design closure flow test,the equivalent diameter of dumped ripraps and reasonable intensity of dumping in the different closure-gap widths were decided.The single-dike direction end dumping closure scheme was recommended ,which provides a scientific basis for implementation of closure work..
