摘　　要：蜀河水电站厂房坝段混凝土施工采用已修建的右岸泄洪闸进行二期导流,需在厂房基坑上、下游修建横向挡水围堰。围堰方案确定前,分别对全年挡水围堰方案和汛期过水围堰方案过流情况进行了水工模型试验,根据模型试验结果确定了二期围堰最终方案为汛期过水围堰方案。Transverse water-retaining cofferdams at both upstream and downstream of powerhouse foundation pit need to be built because the completed flood discharge gate on right bank is applied for Phase Ⅱ diversion so as to have dam sections at powerhouse of Shuhe Hy- dropower Station be concreted. Before determination of scheme for cofferdam, hydraulic model tests on flows are carried out respectively according to scheme for year-round water retaining cofferdam and scheme for overflow cofferdam in flood season. Based on the model test results, the final scheme for Phase Ⅱ cofferdam is the one for overflow cofferdam in flood season.
