摘要

针对位于煤矿采空区的某750 kV输电线路杆塔由于基础发生不均匀沉降出现倾斜的情况

经过对采空区场地现场勘察

采用概率积分法计算预测出采空区地表移动和变形最值等数据

并定性评价塔基的稳定性和安全性

从而提出杆塔扶正的处理措施。经运行验证

采取“更换踏脚结构+加垫板+安装起吊板”技术方案进行的扶正效果较好

可为类似工程提供借鉴。

Abstract

A 750 kV transmission line tower located in the coal goaf inclined due to the uneven subsidence of the foundation.Through site survey of the coal goaf

the probability integral method is used to calculate and predict the maxima and minima of surface movement and deformation.The paper qualitatively evaluates the stability and safety of the tower base

so as to put forward the tower corrective measures.After operation verification

the technical solution of “replacing footing structure plus adding pad plus installing lifting plate” is effective and can provide a reference for similar projects.
