Numerical Analysis of Stress and Deformation Characteristics of L-Shaped and Soil Filled Retaining Walls

The stress and deformation characteristics of a model LShaped, soil filled model retaining wall as well as a conventional LShaped retaining wall was numerically studied by using a commercial finite difference software FLAC3D. The lateral earth pressures acting on both wall types and the lateral deflection of both walls are investigated in this paper. The results indicate that, LShaped and soil filled wall can effectively control the lateral deflections. It is also concluded from the numerical analysis that the stress concentration is occurred at the connection point between the bottom slab and vertical box.
