摘　　要：在岷江龙溪口航电枢纽工程施工导流方案实施阶段,结合施工期导流及通航模型试验成果,对导流方案进行优化调整,将临时航道右导墙左移4孔泄洪闸,三期不利用围堰挡水发电,导流工程节省投资大于减少发电效益,且能有效改善施工期通航条件、降低三期施工压力、提高施工工期保证率,有利于工程建设顺利地推进。In the construction diversion implementation stage of Mingjiang Longxikou Navigation Power Junction project,the diversion scheme is optimized based on the diversion and navigation experimental results.The right guide wall of the temporary navigation channel is moved leftward for a distance of 4 spillway gates.The cofferdams are not responsible for power generation water retaining in the third stage.It shows that the reduced investment of the diversion work is higher than the loss of the power generation benefit.At the same time,the optimized diversion scheme can effectively improve the navigation conditions during the construction period,reduce the construction intensity of the third stage,and greatly improve the assurance rate of construction schedule,which ensure the smooth implementation of the whole project.
