Based on the wedge unit method, the active earth pressure against a retaining wall in the non-limit state is studied. According to the relationship between the displacement of the retaining wall and the mobilized internal frictional angle of filling in the non-limit state obtained by earlier researchers, the influences of the internal frictional angle and the displacement ratio of the wall on the unit active earth pressure coefficient, the distribution of the active earth pressure, and the application point of the active earth pressure in the non-limit state are discussed. Finally, through comparison with experimental data, the distribution of the active earth pressure calculated by the method proposed is shown to agree well with experimental results. Therefore, the method proposed in this paper has theoretical significance and engineering value.

基于楔单元法的非极限状态主动土压力计算

基于楔形单元法，研究了非限制状态下挡土墙的主动土压力。根据早期研究人员在非极限状态下挡土墙的位移与填充物动员内部摩擦角之间的关系，研究了内部摩擦角和挡土墙位移比对单位有效土压力的影响。讨论了非极限状态下的系数，有效土压力的分布以及有效土压力的施加点。最后，通过与实验数据的比较，表明所提方法计算出的有效土压力分布与实验结果吻合良好。因此，本文提出的方法具有理论意义和工程价值。
