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.

Key words: geogrid, reinforced embankment, slope foundation, model test
