| 摘 要： | 提出了用潜在滑移线 (面 )理论分析边坡滑动面及稳定性的新方法。该方法根据弹塑性有限元的应力分析结果 ,用数值积分方法确定边坡的潜在滑移线 (面 )、最危险潜在滑移面和边坡稳定性安全系数 ,具有严密的理论依据。通过大量的边坡算例和实例分析得出 ,本文所提出用潜在滑移线 (面 )理论分析边坡稳定及潜在滑面是正确的 ,具有较强的优越性 ;常规边坡稳定性分析与本文方法所得到的最危险潜在滑移线 (面 )形状和位置、边坡稳定安全系数均相差较大 ,常规法所得到的结果与实际与相差较大 ;岩土的变形参数变化对潜在滑移线 (面 )的形状影响较大 ,对边坡最危险潜在滑移线 (面 )的形状、位置及平均稳定安全系数影响不大 ;坡顶荷载变化对潜在滑移线 (面 )的形状、位置和边坡稳定安全系数均影响较大。

| Abstract: | A new method can be used to analyze the slope slip surfaces and stability is proposed in the paper.It is based on the potential slip surface theory.According to the stress analysis results,it is proved that the method has a rigor basis.The numerical integration is used to make sure of the potential slip surfaces,the most dangerous one,and the stability safety factor of the slope.Through many examples and engineering tests,the proposed method is proved correct and has much advantage.At last,some useful conclusions are obtained. |
