摘　　要：危害性大、治理费用高的滑坡等不良工程地质,是山区公路选线需要考虑的重要因素.文章结合西藏某公路工程实例,以公路桩号K17+400~K17+700段高陡边坡为研究对象,利用现场调绘及工程地质钻探成果分析评价滑坡体的滑动机理,并结合滑坡体岩土物理力学参数,定量分析计算正常、饱水以及饱水叠加地震等不同工况下边坡的稳定性.Harmful and costly landslide and other bad engineering geology are important factors to be considered in the route selection of mountain roads.Combining with a highway project in Tibet,this paper takes the high and steep slope of highway pile No.K17+400~K17+700 as the research object,by using the results of field mapping and engineering geological drilling,analyzing and evaluating the sliding mechanism of the slope,and combined with the physical and mechanical parameters of the slope,analyzing and calculating quantitatively the stability of the slope under different working conditions such as normal,saturated water and saturated water superposition earthquake,and reasonable suggestions,which were put forward according to the analysis and calculation results.
