摘要

采用大型室内模型试验的方法，研究了斜坡地基上一个土工格栅加固的填方路堤和一个未加固填方路堤在坡顶荷载作用下的变形与破坏规律。重点介绍了该模型的试验设计、测试和试验数据分析方法。试验主要测试了填方路堤边坡坡面的水平和垂直位移、填方路堤顶部垂直位移、填方路堤内部应力、填方路堤内部土体位移、填方路堤的破坏面形态等。试验结果表明，加筋能够提高斜坡地基上填方路堤的稳定性及承载力，并且能够大幅减小路堤的水平位移，该模型试验结果对西部山区高速公路的建设具有一定的指导意义。

Abstract

The performance of a reinforced and an unreinforced embankments on mountain slope foundation are studied with full-scale models. The models are surcharged until collapse under load on the embankments crest. This paper focuses on the test design and instrumentation of the embankments on mountain slope. During the experiments

the vertical forces distribution

displacements of slope

the form and position of the slip curve surface in the two embankments are also investigated. The test results show that the geogrid will improve the stability and the ultimate bearing capacity; and the lateral displacements of the reinforced embankment are smaller than that of the unreinforecd embankment. The test resalts are very useful for the expressway design and construction in the mountain region.
