摘　　要：以实际临坡基础输电杆塔边坡工程为依托,采用强度折减法计算了边坡的安全系数,分析了坡角、基础埋深、坡顶距对边坡稳定的影响,并根据灰关联分析方法研究了各影响参数对边坡稳定性影响的敏感性。结果表明,对边坡安全系数影响程度由大到小的影响因素为坡顶距、坡角、基础埋深。Based on an actual slope engineering for slope-side foundations of transmission tower, this paper calculated the safety factor of slope by strength reduction method, studied the impact of slope angle, buried depth and top distance on the slope stability, as well as the slope stability＇s sensitivity to these influence parameters by the grey relation analysis. The result shows that the size order of influence on slope＇s safety factor is top distance 〉 slope angle 〉 buried depth.
