粘性填料加筋土挡墙设计方法研究

Research on Design Methods for Reinforced Earth Retaining Wall with Cohesive Backfill

对于粘性填料的加筋土挡墙的内部稳定分析 ,考虑其破裂面形状为园弧滑面 ,且筋带受力沿筋带埋置深度呈线性分布 ,导出了拉筋受力、筋带长度的计算公式。用该公式进行设计更符合粘性土填料加筋土挡墙的实际情况 。

For the stability analysis of the reinforced earth retaining wall with cohesive backfill, this paper assumes that the state of failure surface is circular sliding surface and the bearing capacity is straight line relation with capacity and length of the reinforcement strip. These formulas agree with actual state of the reinforced earth retaining wall with cohesive backfill and result in saving reinforcement material in the design.
