双级土工格栅加筋土挡墙的测试分析

Test and analysis of two-step retaining wall reinforced by geogrid

通过对梅坎铁路双级土工格栅加筋土挡墙的墙面板水平土压力、垂直土压力及土工格栅变形的原位观测 ,分析了墙面板水平土压力的变化及分布规律、垂直土压力变化及土工格栅的变形随填高及时间的变化规律 。

In this paper,the prototype measurement for the lateral soil pressures on the facing,the vertical soil pressures and the deformations of the geogrid on the two step retaining wall reinforced by the geogrid on Meikan railway, were described.The variation and distribution of the lateral and vertical soil pressures and the deformations of the geogrid with soil filling and time were analyzed,the cracked face of the wall was discussed.
