Abstract：In connection with the practice of a metro tunnel crossing below ground buildings in Shanghai soft soils，the transient and consolidation settlements of the severely inclined building induced by two shield tunnels crossing one after another are analyzed with respect to their distribution and time-dependant features. Furthermore，based on field measurement data of pore water pressure and laboratory experiment on soil behavior under vibration，an estimation method for settlement induced by long-term train vibration during metro operation is proposed to predict the effect on ground buildings. The final settlement concerning both construction and operation stages varies with time and relative position to the tunnel center. These changing features of settlement are in close relation with the damage criterion of building and significantly affect the safety of the building. According to the time and space-dependant features of settlement during construction and operation stages of metro tunnel，corresponding measures for four different stages are suggested to control the settlement effectively. The calculation results of long-term settlement induced by train vibration show that about 80% of the total settlement occurs during the first decade，which indicates that the first decade is the key period to take measures to control settlement.
