Numerous methods have been used in the past and recent time to enhance the bearing capacity of the soils, depending on the type of the structure, available equipments, and the properties of the soil. The use of granular trench (two-dimensional plane strain condition of stone column) is one of these methods. This paper provides a finite element method to model soft cohesive soil, granular trench soil, and the reinforcement material by using a computer program called (SIGMA/W). The behavior of both cohesive and granular soils is simulated by nonlinear-elastic soil model (hyperbolic model), while the linear-elastic model was used to simulate the reinforcement material. The angle of friction of the trench soil, the modulus of elasticity of the reinforcement material, the depth, width and shape of the granular trench, the locations, and number of the reinforcement layers were varied. The sloped granular trench was analyzed in two cases; lined and unlined conditions. The results showed that using of granular trench beneath foundations will increase the bearing capacity and reduce the settlement. Moreover, using of polymers as a reinforcement material has a significant effect on both bearing capacity and settlement. Verification of the program has been made by comparing the program results with the available experimental results in the literature. In general, good agreement was found between the SIGMA/W results and the experimental findings.
