摘要
本文首先分析了在无地下水时重力式挡土墙的各种破坏模式 ,然后运用可靠度理论对挡土墙的失效概率进行了分析计算 ,考虑地下水位和土性参数 ,将其作为随机变量的计算结果能对重力挡土墙的稳定性做出较为客观全面的评价。
Firstly, the failure models of gravity retaining wall without ground water are analyzed in this paper. Then, the failure probability of gravity retaining wall by reliability theory is analyzed as well. Finally, the soil parameters are taken as uncertain variables and the example shows that the method can give a com prehensive judgement of gravity retaining wall.
