摘要

候月线桃坪隧道自建成运营以来,病害持续不断,且从2013年起病害加剧发展,危及行车安全。文章通过对桃坪隧道病害进行系统的专项勘察,采用查阅资料、洞内调查、地面调绘、沿线走访、物探钻探、室内试验等综合手段,对隧道各时期的病害类型、段落、规模及病害发展情况进行了全面排查和统计,查明了隧道病害成因,其主要受建设标准、工程缺陷、围岩软弱及膨胀性、煤矿采空区等多种因素影响所致。结合隧道病害情况,文章提出了天窗点整治、封闭一孔倒换整治、新建一座双线隧道、新建一座单线隧道及封闭一孔扩挖整治等改造方案。综合研究后认为:既有隧道病害整治应采用单线行车、封闭施工的方案,新建隧道宜采用单洞双线隧道方案。
        Since the operation of Taoping tunnel on Houma-Yueshan railway,the diseases occur frequently and have been developing intensely since starting in 2013,endangering traffic safety.With a systematic special survey on the diseases of Taoping tunnel,a comprehensive investigation and statistics were carried out regarding the disease type,section,scale and development in different phases by means of desk study of documents,in-tunnel investigation,ground survey,site visiting,geophysical prospecting,drilling prospecting and indoor tests,and it found out the tunnel diseases are affected by construction standard,engineering defect,weakness and swelling of surrounding rock,mined-out area and other factors.The different rehabilitation schemes were proposed,including rehabilitation at the window time,alternately rehabilitation by closing one tube,building of a new double-track tunnel,building a new single-track tunnel and enlarging excavation by closing one tube and so on.It concluded that a scheme of onetrack tube running and one tube closing is recommended for the existing tunnel rehabilitation and a one-tube twotrack tunnel system for the new built tunnel scheme.
