Design and thinking of the solutions linking between the subway station and 

business building over the subwayLiao Hongwei, Liu Xingkun, Sun Fuping, Zhu Qiang

Abstract: Building commercials on the subway station becomes complex and difficult due to its structure and shield tunnel. Taking Tianjin North Canal Station on metro line six as an example,an analysis on the effect that surrounding buildings was done and settlements on the subway station during the earthquake, based on brief but accurate calculation. Taking the advantage of pile foundation and construction measure such as late poured band， the effect of surrounding buildings settlements on the subway station can be greatly reduced. However, in order to protect the subway station from being destroyed in the earthquake, the hypothesis were made that anti-seismic performance of structural on the subway is superior to that of commercial buildings. In this way, the subway station is still in a state of elasticity when structural of the commercial buildings enter plastic. Therefore it ensures the feasibility of this hypothesis using the method of underground breaking joint and overground no breaking. Besides, some potential problems on building commercials over subway stations and corresponding solutions were present in order to give some references to similar construction.

Keywords: building over the subway; breaking joint; joint construction area; seismic response
