在列车长期作用、周边工程施工扰动等因素影响下, 运营期地铁盾构隧道将出现一系列较为常见的病害现象.对武汉某软土地区地铁盾构隧道运营半年后产生的如隧道渗漏水和冒泥现象、整体道床与管片脱开产生离缝、道床变形缝附近产生贯通横向裂缝、纵向不均匀沉降等常见病害现象, 进行了原因机理分析, 并根据实际的工程地质条件和周边环境, 针对不同的病害特性提出合理的治理措施.%Influenced by the long-term operating load action and the surrounding construction interference, metro shield tunnel in operation period is inevitably infected by a series of common diseases. Combined with some disease phenomenon detected from a practical shield tunnel after 6 months in the soft layer of Wuhan City, such as tunnel leakage and mudding, gaps induced by detachment between integrated track bed and segment, penetration transverse cracks near the deformation joint, longitudinal uneven settlement and so on, the mechanism of the disease causes is analyzed. According to the actual geological conditions and the surrounding environment, reasonable control measures are put forw ard for different disease characteristics.
