摘　　要：山区公路因地形多变、地质情况复杂等原因,极易发生滑坡,严重影响了公路的正常运营。以攀枝花机场路K10+935滑坡治理工程为例,结合研究区地形地貌及工程地质条件,对滑坡成因进行分析,采用传力系数法计算正常工况(天然工况)、非正常工况Ⅰ(暴雨工况)、非正常工况Ⅱ(地震工况)下的滑坡推力,并以此为依据,从前缘支挡(桩板墙)、坡面防护、坡面排水等方面对该滑坡的综合治理进行研究。Due to the varied topography and complex geological conditions,landslides are prone to occur in mountainous road,seriously affecting the normal operation of the roads.Taking the landslide treatment project at K10+935 of Panzhihua Airport Road as an example,this paper analyzes the causes of landslides based on the topographic and geological conditions of the study area.The thrust of landslides under normal conditions(natural conditions),abnormal conditionⅠ(rainstorm condition),and abnormal conditionⅡ(earthquake condition)is calculated using the force transfer coefficient method.Based on these results,a comprehensive study on the landslide treatment is conducted from the aspects of front-edge retaining(pile-sheet wall),slope protection,and slope drainage.
