Reinforcement Effects of Geocell Mattress on Bearing Capacity of Soft Ground

Abstract

A geocell mattress, which takes the interlinked form of three dimensionally build up multiple cells with thin geosynthetics vertical partition walls and the inner parts of which are filled with soils, has wide application such as an improvement of poor bearing power of ground.A series of two dimensional plate loading laboratory model tests was carried out to investigating major influence factors related to the reinforcement of soft clay ground. It was found from the test results that the lower the bearing capacity of supporting ground was, the higher the reinforcement effects were obtained. Moreover the results indicated that the coefficient of bearing capacity and the bearing power were increased with the width of geocell mattress.
