浅谈城市轨道交通隧道结构渗漏的成因与治理

Discussion on the Causes and Treatment of Structural Leakage in Urban Rail Transit Tunnel

随着国家交通运输行业的快速发展,地铁隧道施工技术日趋成熟,地铁隧道越来越普遍。然而,城市地铁隧道由于受建设条件及运营期材料性能劣化、列车振动、周边活动、气候条件等因素影响,导致运营期间出现渗漏水问题,大幅降低了隧道结构的安全性和可靠性,影响地铁安全运营,因此,隧道结构渗漏成因分析与治理显得尤为重要。隧道渗漏水是隧道常见的一种缺陷,直观表现为结构裂缝,成因也比较复杂。因此,本文针对北京地铁19号线区间隧道在运营期间的渗漏水现象进行深入分析与研究,统计了引起渗漏水的病害特性,针对不同的病害采取不同的处理措施,研究总结出了不同的渗漏水病害治理的常用方法,以期为类似隧道衬砌渗漏水的预防和整治提供借鉴。

With the rapid development of national transportation industry,subway tunnel construction technology has become increasingly mature and subway tunnels have become more common.However,due to the construction conditions and the deterioration of material performance during operation,train vibrations,surrounding activities,climate conditions and other factors,urban subway tunnels cause leakage problems during operation,which greatly reduces the safety and reliability of tunnel structure and affects the safe operation of subway,so it is very important to analyze and control the cause of tunnel structure leakage.Tunnel leakage is a common defect of tunnel,which is directly manifested as structural crack,and the reason is relatively complicated.Therefore,this paper conducted in-depth analysis and research on the phenomenon of water leakage in the tunnel section of Beijing Metro Line 19 during operation,counted the characteristics of the diseases causing water leakage,took different treatment measures for different diseases,studied and summarized different common methods of water leakage disease treatment,hoping to provide reference for the prevention and treatment of water leakage in similar tunnel linings.
