摘　　要：针对粘性土回填高挡土墙的土压力计算问题,通过工程实例,分析探讨了用综合内摩擦角法和力多边形法计算粘性土主动土压力的差异性,并引入一折减系数使综合内摩擦角法更完善,以便为工程应用提供参考依据。As for the calculation methods of active earth pressure acting on high retaining wall backfilled by cohesive soil, this paper studied the difference between the internal friction angle method and the force polygon method to calculate active earth pressure. Through the analysis of an engineering example. A discount coefficient to improve the combined internal friction angle method, is presented. It provids reference for future engineering application.
