摘　　要：随城市建设推进,越来越多的高压输电线塔受到基坑开挖的影响,研究近基坑高压输电线塔的变形规律显得尤为重要。以双侧临近基坑的高压输电线塔为研究对象,基坑施工中开展线塔基础沉降监测、水平变形监测及线塔倾斜监测,获取各阶段线塔关键位置变形数据。对不同施工阶段高压输电线塔变形数据分析,总结了基坑施工对高压输电线塔的影响。经多期数据比对分析,研究了近基坑高压输电线塔基础沉降变形及水平变形在基坑施工中阶段性变化规律。对近基坑各建筑物、构筑物的监测及保护提供参考。This article analysised the multi-period deformation data of near-function pit high-voltage tower.In order to obtain the deformation data of the key positions of the high-voltage tower,settlement monitoring,horizontal deformation monitoring,tilt monitoring were taken.Summaried the impact of foundation pit construction on high-voltage tower.Studied the change law of settlement deformation and horizontal deformation during the foundation pit construction.According to meet the requurements,it provides a reference for the implementation of the same type of deformation monitoring projects.
