摘要
某750kV输电线路工程部分塔基位于煤炭采空区内,文章采用概率积分法对采空区地表变形进行了预计,根据变形预计结果对输电线路塔基的稳定性进行了评价,并提出了地表塌陷变形后杆塔应急抢修的处理措施。
Part of the tower foundation of a 750kV transmission line project is located in the coal goaf.In this paper,the probability integration method is used to predict the surface deformation of the goaf,the stability of the tower foundation of the transmission line is evaluated according to the predicted results of deformation,and the emergency repair measures of the tower after surface collapse are put forward.
