西—攀高速公路米易滑坡稳定性评价及治理措施

在建高速公路以路基和桥梁方式从米易古滑坡中前部通过，文章介绍了滑坡的工程地质环境和特性，通过宏观地质条件和作用因素对其整体稳定性进行了评价，在此基础上通过力学计算法对稳定性较差的前级次生滑坡进行了定量评价，指出滑坡对在建高速公路的影响，并提出了工程治理措施。通过对此滑坡治理的成功经验为西南山区高速公路建设地质灾害防治提供了一条新思路。

Stability Evaluation and Treatment Measures of Miyi Landslide along Xichang-Panzhihua Highway

The highway under construction passed through the front part of Miyi landslide by means of subgrade and bridge. This paper introduced the geological environment and characteristics of this landslide and evaluated the overall stability through macro geological conditions and action factors. On this basis, the pre-secondary landslide with poor stability was evaluated quantitatively using mechanical calculation method. Then the impact of the landslide on the highway under construction was pointed out, and engineering treatment measures were put forward. With the successful treatment experience of this landslide, a new concept is provided for prevention of geological disasters during highway construction in southwest mountainous area.
