Abstract: Based on the small scale model tests, the structural performances of ten reinforced and unreinforced slopes were studied , which include two slope angles, 1:1 and 1:1.2; two kinds of geogrids, Tensar 40RE and 80RE; and three different reinforcement layers, zero, one and three layers. Under a strip footing load near the slope crest, the deformations of slopes and geogrids were modeled. The coefficients of reinforcement how to affect the structural performance of embankment slopes were carried out; and the mechanical character of geogrids in soils was derived. It is shown that the geogrid will improve the stability and the capacity of the slope.

Key words: geogrids, reinforcement, embankment slope, model test
