摘要/Abstract

摘要： 本文对一加筋土挡墙进行了有限单元分析，墙后为砂性填土，筋材为聚丙烯工程带。数值分析结果与原位测试的对比分析表明，破裂面近似平面滑动情况，土压力呈线性分布且在墙体下端小于传统理论土压力值。同时，本文还讨论了剪胀性等因素的影响。

关键词: 加筋土挡墙, 非线性有限单元法, 原位观测

Abstract: This paper deals with application of nonlinear finite element method to the analysis of a rein-forced earth wall with sand backfill reinforced with polyropylene stripe,Numerical calculations are com-pared with the results of in-situ obeervations,The analytical results of the wall rupture surface show asimilar condition with that of the classical rankine failure plane. The resulting earth pressure shows afamiliar linear distribution and the eatreal pressure at the base of the wall is less than that obtainedfrom the classiCal theory. Noreover,special attention is paid to the effect of the dilatancy property.

Key words: reinforced earth wall, non-linear finite element methed, in-situ observation
