山区高压输电线路铁塔基础的边坡计算

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”。

Slope Calculation of HV Transmission Tower Foundation at Mountain Areas

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 shearing 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.
