摘要

到目前为止，加筋土挡墙采用的填土大多是砂性土，在这种情况下取得的结果与实测结果较相吻合，但当填土为黄土、中低液限黏土及高液限黏土时，加筋土挡墙失败的例子较多，还有待于进一步的研究。通过对黏土与聚丙烯土工带在不同含水率下进行了不同法向荷载作用的直剪试验，讨论了法向应力、含水率对高液限黏土与筋带之间剪切特性的影响。基于试验结果，对312国道宁镇公路某桥头引道黏性土加筋挡墙的设计及工后状况进行了数值模拟，分析了柔性加筋材料的加筋土挡墙破裂面分布形状，并与规范进行对比。分析了了该加筋挡墙失稳破坏的原因，并对黏土作为加筋土挡墙填土材料时，提出相关的改善措施与建议，对今后类似挡墙的修建具有一定的指导和参考意义。

Abstract

By now

most reinforced soil wall filled by sands can work successfully

but when filled by loess

mid-low liquid limit and high liquid limit clay

the reinforced soil wall can not work naturally. In this paper

systematic direct-shear tests in large direct-shear apparatus were carried out for the clay reinforced by geobelt under different normal stresses and water contents. Based on the test results

one destroyed reinforced soil wall created in Nanjing City of Jiangsu Province is analyzed under design condition and work condition by finite element method. Based on the calculation

the crack line of flexible reinforcement soil wall is analyzed; and some important failure reasons are found and the some essential advise and measures for the clay-filled reinforced earth wall are also brought forward

which is very useful to design and research in the future.
