摘　　要：为合理确定孤山航电枢纽工程二期截流各项水力学参数并制定合理的截流方案,使用丹麦水力研究所(DHI)研制的MIKE 21 FM平面二维非恒定流水流模型进行截流水动力计算,根据计算成果优化截流设计及施工方案。采用双向立堵法进行围堰合龙,左右岸同步进占,并以右岸向左岸进占的方式为主,成功实现了二期截流。总结了此次截流取得的成功经验,为类似工程设计施工提供参考。In order to reasonably determine the hydraulic parameters for the second phase closure of Gushan Navigation and Hydropower Project,and to develop a reasonable closure scheme,using MIKE 21 FM two-dimensional unsteady flow model developed by Danish Hydraulic Research Institute(DHI)to calculate the closure flow dynamics,and to optimize the closure design and construction scheme according to the calculation results.Bi-directional advancing was used for cofferdam closure construction,advancing from both left and ride side and dominated by the way of advancing from right to left.The second phase closure was successfully achieved,and the successful experience of this closure was summarized.The research results can provide reference for the design and construction of similar projects.
