Abstract: Three centrifugal model tests, i.e., unreinforced embankment, gauze reinforced embankment, and dacron reinforced embankment, are performed to study the behaviour of embankments on soft clay. Based on these tests, the distributions of the horizontal displacement and vertical displacement as well as the dissipation of the excess pore pressure in the clay foundation are obtained. The reinforcement mechanism of the geotexile is subsequently investigated, with particular emphasis on the effects of the reinforcement strength on the deformation and stability of the subsoil. Centrifuge test results show that the reinforcement can reduce both the settlement and the lateral displacement of the clay foundation, therefore contribute to the improvement the global stability. On the other hand, to guarantee the effectiveness of the reinforcement, the strength and modulus of the geotexile and those of the soil-geotexile interface should be comparable with each other.

Key words: centrifugal model tests, geotexile, reinforced embankment, soft clay
