摘　　要：借助三维有限元软件,对翻板闸采用不同数量的支座对底板混凝土结构进行受力分析,研究闸门在不同支座数量下对底板混凝土结构应力、应变及位移情况。结果表明:①不同数量闸门支座底板混凝土结构大主应力、应变分布特点比较相似,底板支座大主应力、应变值相对较大部位均在底板中下部位应力、应变集中区域,且数值相差不大,但随着支座数量越多,底板应力分布越均匀。②底板的总体位移方向一致,均以竖向位移为主,底板中后部位移值较小,底板前部位移值较大,总体位移量相对较小。In this paper,the three-dimensional finite element software is used to analyze the stress of the concrete structure of the bottom plate with different numbers of supports for the flap gate,so as to study the stress,strain and displacement of the concrete structure of the bottom plate with different numbers of supports.The results show that:①the distribution characteristics of the large principal stress and strain of the concrete structure of the bottom plate with different numbers of gate supports are similar,the large principal stress and the parts with relatively large strain values are in the stress and strain concentration area at the middle and lower parts of the bottom plate,and the difference between the values is small,but the more the number of supports,the more uniform the stress distribution of the bottom plate.②The overall displacement direction of the bottom plate is consistent,mainly vertical displacement.The displacement at the middle and rear of the bottom plate is small,while the displacement at the front of the bottom plate is large,and the overall displacement is relatively small.
