摘　　要：地铁列车运营安全很大程度上取决于隧道结构的稳定性,为了对上海软土地铁运营隧道结构稳定状态进行评估,为及时进行病害治理提供依据,地铁运营管理部门通过日常巡查、长期监测等手段对地铁隧道结构状况实时监控。根据历年监护经验与成果,文章总结了目前隧道病害的主要形式,初步分析了病害产生的原因,并提出预防病害的相关建议,以期为类似地区运营地铁安全保护提供参考价值。The safety of the operating tunnel is directly influenced by the stability of tunnel structure. To give an accurate evaluation on the structural stability of the operating tunnel and provide practical foundations for further disease healing, related management departments have been undergoing daily supervision and long - term monitor on the tunnel structure. Based on the large amount of information and data about Shanghai subways accumulated in the past decades, the primary forms of tunnel disease are introduced, the causes for the damage are analyzed and the related suggestions for prevention are given. All of the work is expected to give some useful references for the projects in similar conditions.
