Repeated load response of soil reinforced by two layers of geocell

Original language description

This paper describes a series of cyclic plate load tests on a circular plate with diameter of 300 mm, supported on unreinforced and reinforced beds by one and two layers of geocell, to simulate the behaviour of footings or vehicle passes. According to initial studies, the depth of the uppermost geocell layer and of the geocell inter-layer spacing both were selected 0.2 times of plate diameter. The results of the testing reveal the ability of the reinforced system by two layers geocell to 'shakedown' a fully resilient behaviour after a period of plastic deformation. As the number of geocell layers increases, the loading surface deformation of the pavement foundation decreases due, in part, to better load spreading. Under the last cycle of loading at 400 kPa with two layers of geocell (Ng=2), the residual, plastic, deformation is only about 63% of the value for the unreinforced case. Likewise, with increase the number of geocell layers from one to two layers, the pressure transferred to depth of foundation bed beneath the centre of loading plate, considerably decreases. For instance, the vertical stress transferred to a depth of 350 mm beneath the centre of loading surface, under the applied cyclic pressure of 800 kPa, at the end of the load cycles is about 462.8, 321.9, 274.3 kPa for unreinforced and reinforced foundations with one and two layers of geocell, respectively.
