一、引言随着城市化进程的高速推进,城市里高层及超高层建筑逐年递增,对空间利用率的要求越来越高。城市的地上发展空间越来越小,从而导致了大量的地下深基坑的开挖现象发生。考虑到现有基坑支护设计方法及地质条件,支护方案并不能完全保障基坑工程的绝对安全。因此,监测基坑施工的安全是十分必要的。合理利用观测时所采集的变形数据,分析和把握变形体的变形特征和规律,从
I. INTRODUCTION With the rapid progress of urbanization, the high-rise and super-high-rise buildings in cities have been increasing year by year, and the requirements for space utilization rate are getting higher and higher. Urban space for development is getting smaller and smaller, resulting in a large number of underground excavation occurred. Considering the design method and geological conditions of the existing foundation pit support, the support scheme can not fully guarantee the absolute safety of the foundation pit project. Therefore, it is very necessary to monitor the safety of pit construction. Reasonable use of deformation data collected during the observation, analysis and grasp the deformation characteristics and deformation of the body, from
