摘要

提出了采用“土工合成材料加筋+路基注浆+桩支撑”系统的复合地基，并运用于软土地基上路基加宽。采用弹塑性有限元程序分析比较了路堤在加桩和不加桩情况下的沉降大小、不均匀沉降以及土体中的应力水平；特别是桩-土相互作用的计算分析与实测资料的分析比较。得出了一些相关结论，从而为工程实践提供了一定的理论依据。

Abstract

Geosynthetic-reinforced

subgrade-grouting and pile-supported system is proposed to use in widening subgrade. By using an elastoplastic finite element program

the magnitude of settlement

uneven settlement and stress level in the soil mass are compared between two different cases; especially

the pile-soil interaction is analyzed and compared with practice. Base on the analysis results

some conclusions are draw so as to provide the theoretical evidence for practical constructions.
