摘　　要：在地铁开挖过程中,由于受不均匀沉降和沉降速率变化的影响,容易造成建筑物结构出现裂缝,当裂缝宽度变化超出容许值时将严重危及建筑物安全,因此对地铁施工期间建筑物裂缝宽度变化进行全天候、连续、准确的监控具有非常重要的现实意义。运用先进的物联网传感技术,通过裂缝传感器实现裂缝宽度变化全天候、连续性在线监测,并结合云计算平台服务器实现数据实时存储,可对数据进行快速的量化分析,实现高效、动态监控,从而保证建筑物的正常使用。The differential settlement and subsidence rate in subway excavation process can easily cause cracks in the building structure. When the crack width exceeds the allowable value change, it will seriously endanger the safety of the building. As a result, the all-weather, continuous and accurate monitoring on building crack width change during subway construction is of practical sig- nificance. This research uses the advanced lOT sensing technology and realizes all-weather, continuous online monitoring crack width change through crack sensors and real-time data storage with cloud computing platform servers. Also, it can realize the effi- cient and dynmnic monitoring based on the rapid quantitative analysis of the data in order to ensure the normal use of buildings.
