摘要
分析了地震力的偏角及边坡的几何和物理特征对土质边坡地震稳定性的影响,探讨了不同分析方法计算得到的安全系数的差异.结果表明:当地震力与边坡的主滑方向一致时,此时对应的安全系数最小;内摩擦角较内聚力对边坡的地震稳定性的影响更加显著;不同的分析方法得到的安全系数各异,在工程实践中建议采用Janbu法来分析边坡的地震稳定性.
The angles of seismic force and geophysical characters and geometrical property to the dynamic stability of slope are studied,and the differences of safety factor obtained by different analysis methods are discussed.The result indicates that when seismic force direction conform to the sliding direction,the safety factor tend to minimum,and the angle of internal friction has a great influence to the dynamic stability of the slope.Owing to the safety factor obtained by different analysis methods is diverse,it is suggested that the Janbu method should be used to analyze the dynamic stability of slope in practice.
