摘　　要：荆门市东宝山隧道自建成通车以来饱受洞身渗漏水之困,本次整治在查明隧址区地质条件和隧道病害特征,并深入分析渗漏水病害形成机理的基础上,针对性地开展了以排为主,防、截、堵、排相结合为原则的综合整治工作,包括套拱与二衬间增设排水盲管、衬砌背后脱空注浆、增设钢筋混凝土套拱等,消除了原隧道存在的严重渗漏与安全隐患。The Dongbaoshan Tunnel in Jingmen City has been suffering from water leakage since it was completed and opened to traffic.Based on the geological conditions of the tunnel site,the characteristics of the leakages,and the in-depth analysis of the formation mechanism of the water leakage,comprehensive renovation work has been carried out,based on the principle of taking drainage as the main measure,and combining prevention,interception and blocking.The comprehensive treatment,including the addition of drainage blind pipes between the cover arch and the secondary lining,grouting of void behind the lining and addition of reinforced concrete cover arch,eliminates the serious leakage and potential safety hazards of the original tunnel.
