摘要
通过对西安市区进行勘察确定的地裂缝有14条之多,地裂缝成为严重影响西安地铁施工及运用的一种典型的地质灾害。根据西安地裂缝空间展布及其活动特征,针对地铁隧道上、下盘垂直位错、结构变形、上部地表变形、结构下部脱空等安全隐患设计了合理的安全监测方案,为地铁区间隧道及地下结构的结构设计和灾害预警提供了依据,确保了地铁隧道的安全运营,同时这些监测手段及数据为类似工程建设提供工程了经验。
Based on the survey of the Xi＇an city there are more than 14 ground fissures,ground fissure has been a typical geological disaster which has a serious impact on the Xi＇an Metro construction and operating. On the basis of ground fissure＇ s characteristics of spatial distribution and activity,combining with the correlation rules of subway tunnel settlement deformation and ground fissures,this paper designs a security monitoring scheme of upper and lower vertical dislocation,structural deformation,the upper surface deformation,the substructure of void in metro tunnel reasonably,provides a basis for structure design and disaster warning of subway tunnel and underground structure. It ensures the safe operation of subway tunnel,and the monitoring methods and data can provide engineering experience in similar engineering construction.
