摘　　要：大江截流是工程施工阶段转换的重要标志。硬梁包水电站大江截流流量主要受上游泸定电站发电及泄洪影响,截流过程中根据现场情况及时调整方案,丁坝长度增加至100 m,经现场测算,导流明渠的分流比已超过80%,为大江截流创造了良好的条件。根据河床流量由单向进占调整为双向进占方式,从而快速合龙,迅速加高培厚围堰,确保快速截流。研究成果可为同类工程提供一定参考。River closure is an important symbol of the transformation of project construction stage.The river closure flow in Yingliangbao Hydropower Project is mainly affected by the power generation and flood discharge of the upstream Luding Hydropower Station.During the closure process,the scheme is adjusted according to the site conditions,and the length of the spur dike is increased to 100 m.According to the field measurement,the diversion ratio of the open diversion channel has exceeded 80%,which creates favorable conditions for the closure.According to the river bed flow,the one-way advance is changed to two-way advance,so as to achieve the purpose of rapid closure,rapid heightening and thickening of the cofferdam,and then ensure rapid closure.The research results can provide certain reference for similar projects.
