摘　　要：经过计算分析和多年的实践可以认为,按岩石抗剪面计算的山区高压输电线路铁塔基础的边坡数值每缺少1 m,其基础在原设计深度上加深0.3 m是可靠的做法。当对于缩短线路路径、节省工程造价、减少工程量、缩短工期有很大意义时,不妨主动设计"悬挂在峭壁上的子母基础"。Through calculation and analysis, as well as many years＇ operation practice it is a reliable way that slope value of mountainous HV transmission tower foundation calculated based on rock sheafing area is reduced by 1 m, the foundation depth should be added by 0.3 m to the original design depth. If there is a great significance to reduce the line routine, save engineering cost, reduce work volume and construction schedule, it might design a ＂primary and secondary foundation suspended on the cliff＂ on own initiative.
