煤矿采空区对输电线路塔基稳定性的影响

摘要

in the coal mining area the erection of transmission lines exist great risk, how to correctly and objectively evaluate its impact, directly affect the line security and investment cost, this article from the start with the failure mechanism of coal mining area, thickness ratio method, the critical depth of mining empty area and the actual mining depth comparison method and probability integral calculation by using the method of mining in a transmission line, through the mining area and the future mine tower goaf stability is analyzed, the runtime verification, evaluation results are good, can learn from.%在煤矿采空区架设输电线路存在很大的风险,如何正确客观评价其影响,直接影响线路安全和投资造价,本文从煤矿采空区的破坏机理入手,通过采用采厚比法、采空区临界深度与实际采深比较法和概率积分计算法,对某输电线路经过的采空区和未来采空区杆塔进行了稳定性分析,经运行验证,评价结果较好,可以借鉴.
