本站原创Abstract： It is difficult to oid the high filling and excation section in process of freeway construction in mountainous areas. It is because of the slope of mountain digging disturbance that makes the stress concentration release， then causing landslides， collapse and other engineering geological disasters. Take the treatment of high slope landslide at K8+920～K9+160 in the freeway from Baoshan to Tengchong山区高速公路差异风化边坡工程滑坡治理相关论文由www.shuoshilunwen.com收集,如需论文. in Yunnan Province as an example， stability analysis of landslide he done by modeling combined the field investigation and experimental data， and put forward comprehensive control scheme for the same lithology but different weathering obvious engineering landslides. Showing the necessityof that when we put forward the treatment of this kind of engineering landslide analysis in highway construction process， we he to consider the actual geological conditions and reasonable selection of mathematical. And providing reference for engineering treatment for the same type of landslide.

滑坡是指斜坡上的岩土沿坡内一定的软弱带（面）作整体地向前向下移动的现象[1]。自然坡体在开挖卸载后，坡体应力得以释放，坡体稳定性下降，在不利情况如强降雨等因素诱发下，容易产生工程滑坡，山区高速公路建设中经常遇到此类情况[2]。近年来，我国公路建设有了较快发展，尤其是随着高速公路向山区的延伸，公路建设中遇到的高边坡与滑坡、长大埋深隧道等复杂艰险的工程地质理由也越来越多[3]。并且山区特殊的地形和地质环境，高边坡开挖很容易引起边坡变形导致滑坡等灾害的发生，既会增加工程投资延误工期，还会给运营安全留下隐患[4]。因此，山区高速高速公路建设中出现的高边坡与工程滑坡等病害，也越来越受到交通主管部门及建设单位的重视。针对这种情况，如何根据实际的边坡工程地质情况，选用合理的策略灵活治理滑坡以保证边坡稳定，已成为山区高速公路建设中的重点工作。
以云南省保山至腾冲高速公路K8+920～K9+160段高边坡工程滑坡治理为例，通过数理建模完成滑坡稳定性分析，依据现场勘察和滑坡状况，提出了针对该路段同种岩性、不同风化程度和表征状态的工程滑坡处理方案，并取得了理想的治理效果，为山区高速公路滑坡的类似治理工程提供实践经验和参考比较。
