根据实际工程的资料采集和调研分析,总结了高寒地区岩质边坡的典型破坏模式,得出了影响高寒地区岩质路堑边坡稳定性的因素。采用大型通用有限元软件ANSYS和极限平衡分析程序GeoSlope,对有代表性的边坡工程,分析了边坡的形态(坡高、坡比、台阶宽度、台阶高度)、岩体结构(软弱结构面)、冻融循环(冻胀力、水对岩体的软化作用)等对边坡稳定性的影响,根据分析结果提出了治理措施。将提出的治理措施应用于实际工程,效果良好。
According to the actual project data collection and investigation and analysis, the typical failure mode of rock slope in alpine area is summarized, and the factors that affect the stability of rock slope in alpine area are obtained. Using the general finite element software ANSYS and the limit equilibrium analysis program GeoSlope, the slope shape (slope height, slope ratio, step width, step height), rock mass structure (weak structure surface ), Freeze-thaw cycles (frost heave, softening effect of water on rock mass) and so on. According to the results of the analysis, some measures are put forward. The proposed control measures applied to the actual project, the effect is good.
