摘　　要：某输气干线工程分两次穿越珠江,设置始发竖井和接收竖井各2座,竖井均采用地下连续墙内加支撑环板结构,论文通过对竖井进行平面和空间有限元数值模拟分析,并与现行推荐的弹性地基梁法的计算结果进行比较,空间三维有限元分析更能体现圆形地下连续墙与内支撑的变形协调和共同承担荷载能力。The gas transmission project traverse Zhujiang River twice and two starting and two receiving shafts are deployed.The shaft adopt diaphragm wall with inner bracing system structure.After analysis of 2D and 3D finite element calculation and comparison between recommended elastic foundation beam method,3D finite element present better deformation coordination and common load bearing capacity.
