In this study, infiltration process of unsaturated soil by rainfall were examined by experimental model tests. Also. TDR(Time Domain Reflectometer) sensors and direct shear tests were used to verify the change of unit weight, cohesion and internal friction angle induced from water changes in soil. As a result, the water content in soil induced the increase of unit weight and internal friction angle of unsaturated soil by the rainfall infiltration, and it decreased the cohesion in soil. The behavior of in-situ reinforced wall due to rainfall infiltration was calculated by FEM(finite element method). To do FEM analysis, the input data are determined through experiments. The unsaturated state, several items of reinforced wall was examined, which were the stress and axial force acting on the grid, shear strength variations. After that, they were compared to those of saturated condition. It was concluded that in-situ reinforced wall has a sufficient safety factors and the blocks of wall are able to endure cracks. The axial forces acting on the grid show stable behaviors.
