水绥公路阶梯边坡强度参数反演分析

云南省水绥二级公路某路段为阶梯形人工松散质岩质边坡．根据该路段典型的边坡削面形状，结合儿体的工程地质条件，用极限平衡法进行搜索，分析其局郎及整体最危险滑移而．计算结果表明：最危险滑移面往天然和饱水软化条件下的安全系数均小于1．0，坡体均不稳定。从该边坡目的的状态看，它是稳定的，而且历史上降雨作用下也没有滑塌记录，针对这一问题，通过对松散体强度参数进行反演分析，最后给出了建议的参数值，为该路段边坡的稳定性评价分析提供可靠的技术支持。

Back-Analysis of Strength Parameters of Stepped Cut Slopes in Shuisui Highway

Stepped cut slopes in loose rock masses were constructed adjacent to the Shuisui Highway,Yunnan Province.Based on the typical slope cross sections and typical subsurface geotechnical conditions,both the local and overall critical slip surfaces are computed by using the limit equilibrium search method.The results indicate that the factors of safety under both natural and fully softened conditions are less than 1.0.The constructed stepped cut slopes appear to be unstable.However,it is observed that current sl...
