摘要：
The distribution law and calculation method of earth pressure have always been a difficult problem in the research of reinforced retaining wall. In this paper, the magnitude and distribution law of active earth pressure of reinforced earth retaining wall under different working conditions are explored by using the numerical simulation finite element method. Combined with the dynamic play of the internal and external friction angles, a calculation method of earth pressure under non-limit state is proposed, and it is compared with the traditional theoretical formula solutions, finite element numerical solutions and measured results to verify its rationality. The results show that the numerical value of the earth pressure of the retaining wall is affected by the stiffness and the number of layers of the geogrid, showing a general trend that the earth pressure gradually decreases with the increasing of number of the reinforcement layers and the stiffness. The earth pressure of the retaining wall is negatively correlated with the depth. The earth pressure of the reinforced earth retaining wall varies slightly with the depth under different working conditions, and the reinforcement effect is mainly reflected in the upper part of the retaining wall. The non-limit state calculation results obtained by using the improved empirical formula are consistent with the measured results, which proves that the improved formula is reasonable. ©2022 Journal of Northwestern Polytechnical University.
