摘　　要：通过ABAQUS有限元分析软件对圆沉箱弧形仓格、扇形仓格在填料为块石或中砂时,分别进行了数值分析,并对比了数值模拟结果与现行规范矩形仓格的计算结果。分析表明有限元模型计算所得的沉箱中上部水平贮仓压力比规范公式计算值偏小,仓格底部模拟值大于规范公式计算值。工程设计中应将规范公式计算结果适当修正后采用。ABAQUS finite element software is used to analyze the arc-shaped and fan-shaped caissons respectively subject to rubble or moderate sand as the fillings,and the numerical simulation results are compared with the calculation results of rectangular caisson according to current code.The analysis shows that the horizontal ballast pressure acting on the middle and upper parts of the caisson obtained through the finite element model is less than the value calculated by the standard formula,and the simulated value at the bottom of the caisson is more than that by the formula.Thus the calculation results by the formula shall be properly corrected before application in the engineering design.
