| 摘 要： | 通过有限元的方法对路堤荷载作用下刚性桩复合地基的力学性状进行了研究，主要考虑了路堤的高度、宽度以及压缩模量，以及桩体的压缩模量与复合地基置换率等因素的影响。利用ABAQUS通用有限元程序建立路堤荷载作用下刚性桩复合地基的力学模型，重点研究了以上几个主要因素对桩土荷载分担的影响和对桩身应力的影响，对比了柔性基础下和刚性基础下复合地基力学性状的差异。

| Abstract: | By using the finite element method, the mechanics behavior of composite ground improved by rigid piles under flexible foundation is studied. And the main influence factors such as the height and the width of embankment, the compression modulus of embankment and piles, replacement ratio, the replacement ratio of piles are considered. By using the ABAQUS finite element program, the model of the composite ground improved by rigid piles under embankment is established and the main influence factors are analyzed, and the mechanics behavior of composite ground between the flexible foundation and the rigid foundation is compared. |
