摘 要: 针对煤矿开采对采空区上高压输电线路安全运行的威胁和危害,在深入研究煤矿采空区地表变形的一般特征,煤矿开采对采空区上输电铁塔造成的影响,采空区发生地表变形时铁塔塔身、塔基加固纠偏方案的分析,煤矿采空区输电铁塔两大类加固纠偏方案的比较,以及国内外采用的治理方案的基础上,提出一套采空区上输电铁塔加固与实时纠偏技术的设想。利用连通器原理辅助铁塔实时纠偏技术将铁塔基础连为整体,同时及时消除或减小不均匀沉降对铁塔造成的影响,并推荐了铁塔加固与实时纠偏的综合方案,从而进一步降低输电铁塔加固、纠偏的工程造价,更好、更及时地保障输电铁塔的安全。
关 键 词: 结构工程;加固与实时纠偏;连通器原理;煤矿采空区;输电铁塔

Abstract: To eliminate the damage to secure operation of high voltage (HV) transmission line which is caused by exploitation of coal mine, the general features of coal goaf ground deformation, the impact of coal mining on HV transmission towers, the analysis of the reinforcement and rectification scheme of tower footing and body when ground deformation happens in goaf, the comparison of two kinds of schemes of reinforcement and rectification of coal goaf transmission tower, and the governance programs used at home and abroad are studied in depth. A tentative idea of a kind of technology to reinforce and real-timely rectify the transmission towers erected above the goaf is put forward. By using the principle of communicating vessels, real-time deviation-correcting technology will connect the tower footings as a whole, and timely eliminate or reduce the influence of uneven subsidence on tower. And an integrated program of reinforcement and real-time rectification of HV transmission towers is recommended to reduce the cost of reinforcement and rectification of transmission tower further, and safeguard the safety of transmission tower better and more timely.
Key words: structural engineering; reinforcement and real-time rectification; law of communicating vessels; coal-mining area; transmission tower
