摘　　要：随着越来越多的大尺寸、高水头水工建筑物陆续投入运行,其在适应特殊地形地质条件的同时,常规结构型式应力、位移过大等问题也日益突出。本文以碾盘山水利枢纽泄水闸为研究对象,利用ANSYS有限元软件,对泄水闸常规结构型式及优化后结构型式分别进行分析计算,计算结果表明,半框架结构能有效减小大尺寸、高水头泄水闸的应力和位移,可为类似泄水建筑物结构设计参照。As more and more large-scale,high-head hydraulic structures are put into operation,their adaptation to special terrain and geological conditions often highlights the problem of excessive stress and displacement in conventional structural forms.This paper takes the sluice gate of the Nianpanshan Water Conservancy Project as the research subject,and uses ANSYS finite element software to analyze and calculate both the conventional structural form and the optimized structural form of the sluice gate.The results demonstrate that the semi-frame structure can effectively reduce the stress and displacement in large-scale,high-head sluice gates,and can provide a reference for the structural design of similar sluice structures.
