摘　　要：通过对影响挡土墙抗倾覆稳定性问题的深入分析 ,提出了一种引入挡土墙主动土压力分项系数进行挡土墙抗倾覆稳定性验算的新方法。该方法将挡土墙的地基承载力验算与抗倾覆稳定性验算合并 ,概念清晰且计算结果可靠 ,并能与现行《建筑结构可靠度设计统一标准》(GB 5 0 0 68— 2 0 0 1 )及《建筑结构荷载规范》(GB5 0 0 0 9— 2 0 0 1 )Through analyzing the factors influencing the retaining wall's anti?overturning stability, putting forward a new method with introducing the partial factor of retaining wall's active earth pressure to deal with the checking computation for retaining wall's anti?overturning stability. In this method, the checking computation for ground bearing capacity and the checking computation for anti?overturing stability have been united. The concept is clear and the consequence is reliable, moreover, it is consistent with the 《Unified standard for reliability design of building structures》(GB 50068—2001) and 《Load code for the design of building structures》(GB 50009—2001).
