地下空间改造对相邻地铁变形影响分析

Effect Analysis of Underground Structure Reconstruction on Adjacent Subway Deformation

结合工程实际,通过对影响地铁结构稳定和安全的因素进行分析,采用外部环境监测配合地铁结构变形自动化监控的技术方法,掌握地铁工程结构的变化。结果表明:通过对地铁结构内外因素的一系列监控,在保证地下空间改造正常施工的同时,避免了对临近地铁产生变形、沉降等影响,有效保证了地铁结构的安全稳定以及地铁线路的正常运营。

Combined with an actual project, factors that influence the stability and safety of subway structures were analyzed and the change of subway structural state can be controlled by monitoring the external environment together with automatic monitoring of the subway structure deformation. The results show that with a series of monitoring to all the internal and external factors that influence the subway structure, the influences of nearly underground renovation construction to subway structures such as deformations or subsidence were successfully avoided. The structural safety as well as the normal operation of the subway lines was guaranteed during the renovation construction.
