摘　　要：利用Plaxis 2d AE软件对印尼常用的软土路基处理方法:竹桩-竹排垫层进行有限元分析,探讨其作用功能,考虑土体蠕变对工程沉降结果的影响,并利用二维数值模拟结果,分析实际施工期间土体的沉降变形,保证路基填筑期间稳定,以便安全指导工程施工,为后续工程提供经验。Plaxis 2d AE is used to conduct finite element analysis of the treatment method of soft soil subgrade commonly applied in Indonesia,namely,bamboo mattress-pile structure.Its performance is also explored.Considering the influence of soil body creepage on engineering settlement results,2D numerical model can be used to simulate and analyze the settlement and deformation of soil body during construction,which ensures stable subgrade during filling,guides safe construction,and provides experience for subsequent projects.

关 键 词：Plaxis软件 竹桩-竹排垫层 软土蠕变 路基填筑
