摘　　要：通过对一典型3层地下环形车库坡道设计为案例,使用理正结构设计软件以及盈建科三维有限元软件计算分析对比外墙弯矩分布规律,得出外墙设计中考虑到支座处对于外墙的支撑作用较弱,支座处的弯矩并不大,底板对于外墙的嵌固作用较强,支座弯矩较大.对于环形坡道地下室外墙,有必要进行三维有限元计算,通过与理正计算的弯矩数值进行包络设计更加合理,并为相关类似工程提供参考。Taking a typical three story underground circular garage ramp as the case, the bending moment distribution law of exterior wall is analyzed by using Lizheng structural design software and YJK three-dimensional finite element software. The support has a little effect on the exterior wall resulting in the small bending moment;the bottom plate has a embedding effect on the outer wall resulting in the large bending moment. For circular ramp basement exterior wall, it is necessary to carry out three-dimensional finite element calculation. The envelope design is more reasonable by comparing with the bending moment calculated by Lizheng, providing reference for relevant similar projects.
