摘要
煤矿采空区地质塌陷而产生杆塔倾斜与基础差异沉降问题已成为全国电力行业关注的热点安全问题,倾斜与沉降而产生的非荷载应力将极有可能导致杆塔构件破坏、断裂、变形等事故发生,对输电线路的安全运行构成严重威胁。从减灾防灾的角度采取有针对性地治理维护措施,提出采空区输电线路运行维护方法、处理措施及建议。
Tower tilting caused by land subsidence at coal mined-out area and by subsoil differences has become the key issue concerned by electric power industry. The non-loading stress on tower caused by tilting and settlement might lead to fracture and deformation of tower, which poses a severe threat to the secure operation of transmission lines. In this paper, measures and suggestions are put forward to maintain the transmission lines at mined-out area.
