摘　　要：本文以左江水利枢纽的泄流条件为依据 ,进行二元水流试验研究 ,从水流流速分布、河床受冲程度、下游波浪的大小 ,提出了低坎分流墩的关键体型参数的较优值 ,并利用有限元对分流墩优化前后的体型进行了受力分析 ,提出了一种适用于实际工程应用的分流墩体型。In order to attain the optimized form of diffluent piers with low ridge,some experiments have been made according to the hydraulic conditions of the Zuojiang river.Some key parameters of the diffluent piers have been put forward by analysis of the velocity distribution, the extent of erosion in the river bed and the wave conditions in the downstream.After analysis of the diffluent piers types by finite element method,the optimization type of diffluent piers in favour of the engineering application is acquired.
