摘　　要：以某绕城公路扩建工程为背景,采用二维弹塑性有限单元法分析了采用深层搅拌桩隔离墙处理扩建部分软基的适宜性。分析结果表明深层搅拌桩隔离墙的加固方案是可行的,并且综合考虑施工可行性、成本经济性等,提出了适宜的墙体宽度、强度要求及其墙体的最佳设置位置。Based on an urban bypass expressway widening project, the finite element technique using a Mohr-Coulomb elastic-plastic constitutive model was applied to analysis the feasibility of using diaphragm wall to improve the soft clay. Conclusions are achieved that the diaphragm wall should meet with the requirement.Moreover, the appropriate location, strength and thickness of the diaphragm wall were put forward.
