摘要: 针对挡土墙底部为逆坡、折线边坡、土坡圆弧滑动破坏等特殊情况,根据不确定荷载的性质、作用结果等因素,探讨了不同安全系数计算表达式,给出了推荐公式。通过抗滑稳定安全系数计算模型分析表明:在抗滑力大于滑动力、滑动力大于不确定荷载情况下,不确定荷载作为抗滑力考虑得到的安全系数小,而作为滑动力考虑得到的安全系数大。

关键词: 抗滑稳定, 滑动力, 抗滑力, 不确定荷载, 安全系数

Abstract: The different sliding factory of safety in the retaining wall design under various loading conditions are presented in this paper. These conditions are: reverse slope at the bottom of a retaining wall; segmental lined slope failure mode; and circular failure mode. The factor of safety calculation formulas are proposed. The case history calculation these methods are reasonable.
