    摘要:

    随着国家交通建设的飞速发展,铁路、公路等线状工程中的隧道将不可避免地要穿越采空区。采空区上覆岩体的位移和变形直接影响既有隧道结构的整体稳定性,采空区沉降过大时,将导致隧道衬砌开裂、掉块、路面下沉,严重危及行车安全。现对目前隧道下伏煤矿采空区病害的研究进展进行综合评述,在肯定以往研究成果的基础上,对现有研究工作进行深入剖析,分析其存在的问题和局限性。基于当前的技术水平,结合工程实践,对既有隧道下伏采空区病害的探测手段、产生机理和治理方法进行技术展望。

    Abstract:

    With the rapid development of national traffic construction, tunnels in linear projects such as railway and highway will inevitably pass through the goaf. The displacement and deformation of the overlying rock mass in the goaf directly affect the overall stability of the existing tunnel structure. If the goaf settlement is too large, it will lead to the cracking of the tunnel lining, the falling of the block and the subsidence of the road surface, seriously endangering the traffic safety. This paper gives a comprehensive review on the research progress of goaf diseases in coal mines under tunnels, and makes an in-depth analysis of the existing research work on the basis of affirming the previous research results, and analyzes the existing problems and limitations. Based on the current economic and technical level, combined with the engineering practice, this paper makes a technical outlook on the detection means, generation mechanism, and treatment methods of the goaf diseases under existing tunnels.
