加筋边坡在坡顶荷载作用下的极限承载能力

Study on ultimate bearing capacity of reinforced slopes with full-scale model test

采用大型室内试验的方法,研究了两个土工格栅加固的土坡和一个未加固边坡在坡顶荷载作用下的变形与破坏规律。本文重点介绍大型模型的实验设计、测试技术和研究方法。实验结果表明,土工格栅加固边坡的承载能力为相同条件下未加固边坡的1.6-2倍。

The performance of two reinforced and one unreinforced slopes was studied with full-scale models. The models were surcharged until collapse under a strip footing near the slope crest. The paper focuses on the test design and instrumentation of the slopes. The test results snow that the ultimate footing bearing capacity of reinforced slopes with geogrid reinforcement is about 1.6-2 times that of the identical unreinforced slope.
