Abstract:
Many risks would be encountered during excavation of deep and largescale foundation pit in complex and sensitive environment, consequently, rational design scheme is very important. In view of 2 deep and largescale foundation pits in complex and sensitive environment, a series of technologies, i.e., retaining structure mode, support arrangement mode, groundwater treatment and automatized metro monitoring, are taken to guarantee the safety of foundation pit and surrounding environment with consideration of geology, hydrology, surrounding environment, shape of foundation pit and convenience. The monitoring results of foundation pit and surrounding environment are analyzed, and the analytical results show that the surrounding environment of deep and largescale foundation pit in complex and sensitive environment should be well recognized, detailed calculation should be carried out, the calculation deviation should be calculated with emphasis, and corresponding countermeasures should be adopted for important risk source timely.
Key words: complex and sensitive environment, deep and largescale foundation pit, metro protection, foundation pit design, Midas finite element calculation, automatized monitoring
