| 摘 要： | "重力式加筋土挡墙"在实际工程中已有不少应用,但由于缺乏对其工作性能的系统研究,目前我国相关规范尚无其设计方法,实际工程中一般根据经验设计,缺乏理论依据。采用FLAC2D程序,模拟一个施工顺序为"先筑墙,后填加筋土"的重力式加筋土挡墙,分墙后填土到墙顶和墙顶堆载完成两个阶段,分析加筋土工格栅对挡墙的水平位移和墙后填土的水平位移、水平应力的影响;土工格栅拉力及拉应变随墙后填土和墙顶堆载的变化。在此基础上,对采用"先筑墙,后填加筋土"工序的重力式加筋土挡墙墙后土压力的计算方法提出了初步建议。

| Abstract: | Geosynthitic-reinforced soil gravity retaining wall(GRSGRW) has been applied more and more to the practical engineering projects in recent years.Due to be short of systematically research on the working properties of the new retaining wall system,the design theory and method for GRSGRW in the relative codes in China are not yet regulated;so some design methods based on experiences,which are short of the theoretical foundation,have to be applied to the design of GRSGRW.In this paper,taking a construction seq... |
