SETTLEMENT EVALUATION OF GEOSYNTHETICS-REINFORCED FOUNDATIONS

Abstract

Based on the hyperbolic load versus settlement relation, a method was proposed for predicting the settlement of foundations reinforced with combining geosynthetic and sand mat. The method was characterized by taking not only increase in bearing capacity but also increase in stiffness of foundations into consideration. The calculated results indicate that the reduction of settlements of foundations due to reinforcement with geosynthetics is given as a function of the initial safety factor without reinforcement, bearing capacity increment ratio and stiffness increment ratio.
