Abstract
In this paper, a case study is considered to study the behavior of a 3.6 m high MSE wall reinforced with geogrid reinforcement. Reinforcement spacing is 0.6 m. A limit analysis has been carried out using LimitState:GEO (which used discontinuity layout optimization DLO) to study the performance of a full-scale wall. The maximum reinforcement tension at each level was computed and the results are compared with the measured values. Computation of load coming on reinforcement under different surcharge load is done by analytical approach using MATLAB. In this paper analytical model (current AASHTO Simplified Method) are also prepared with different surcharge loading. The computed values of maximum load on reinforcement are finally compared with the measured values. The results show the LimitStateGEO analysis gives a better estimation of the maximum reinforcement tension compared to the measured values.
