中文摘要：
根据昆明某石灰岩路基边坡破坏特征及附近采石场剖面特征,分析了该边坡演化过程和失稳机理,并据此提出了边坡支护建议.研究结果表明：边坡演化包括地质构造控制边坡裂隙发育、石灰岩溶解和红土覆盖层形成三个过程;边坡失稳机理为：边坡蠕动变形造成框格梁开裂并丧失其护坡作用,植被促进了边坡演化且不利于边坡稳定,降水最终诱发了边坡失稳.基于其演化过程和失稳机理,防水是该边坡支护的首要任务.
英文摘要：
According to the failure characteristics of certain limestone roadbed slope in Kunming and the profile characteristics of the nearby quarry, its evolution process and instability mechanisms are analyzed, and some advices of the slope supporting are given based on above conclusions. The results show that the evolution process of the slope is the fracture development controlled by geologic structure, the corrosion of limestone and the formation of overlying red clay. The instability mechanisms of the slope are the cracking of the frame beam and the loss of supporting function because of the creep deformation of the slope, the vegetations accelerating the evolution process of the slope which is adverse to the stability of slope, and the rain fall inducing the instability of the slope finally. Based on the evolution process and instability mechanisms, the waterproofing is the paramount assignment of the limestone slope supporting.
