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。结合弹塑性有限元程序,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。
Geosynthetic-reinforced, subgrade-grouting and pile-supported system can be used in widening subgrade. By using an elastlc-plastic finite element program,the magnitude of settlement, uneven settlement and stress level in the soil mass are compared with two different cases; especially analysis of pilesoii interaction in calculation and practice. Base on the analysis results, some conclusion are obtained, which can provide the theoretical evidence for practical constructions.
