我国边坡工程数量众多,具有地质条件复杂、岩土体离散性和复杂性等特点,边坡稳定性是一个多因素相互作用、协调发展的复杂系统问题,其中如何确定合适的边坡稳定性判据是一个具有重要意义和价值的研究工作.在研究了分析常见的边坡稳定性评价方法后,基于监测资料从多个角度来挖掘边坡的变形破坏情况,构建了以变形控制指标为主,辅以其他监控指标的体系,来探讨边坡稳定性的判据和变形控制阈值.最后将该研究成果应用于实际边坡工程中,具有很好的效果,为确保整个工程的安全提供了技术依据和科研支撑.%A number of large slope engineering exist in China which have complex geological conditions.So slope stability is a complex problem of multifactor interaction and coordinated development,among that appropriate criterion of slope stability is an important issue.In this paper the common stability evaluation methods were analyzed first,after which slope deformation and failure excavated from plurality angles,deformation control threshold and stability criterion of slope at different stages were proposed by settlement control indicators and supplement other monitoring indicators.Finally the results were applied in thepractical slope engineering and good effects were acquired.
