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。
According to the special circumstances such as the reverse slope, the broken line slope and the circular arc failure of the earth slope on the bottom of the retaining wall, the formulas for calculating the different safety factors are discussed according to the factors such as the nature of the uncertain load and the result of the action. The analysis of the calculation model of anti-sliding stability and safety factor shows that the safety factor of uncertain load as anti-slide force is small when the anti-sliding force is greater than the sliding force and the sliding force is greater than the uncertain load, but the safety factor considered as the sliding force Large coefficient.
