A triangular transfer hall is planned be built to distribute passenger flow rationally and improve multi-line transfer capability in the city of Shanghai, China. A large-scale reinforced-concrete bracing system, which is established to ensure the stability of the foundation pit, will be demolished with the completion of foundation pit. The influences of construction vibration on the surrounding environment are concerned. An evaluation method, which is generally applied to the ground vibrations caused by operation of machines, road and railway traffic, and construction activities such as piling and blasting, is then extended to assess the ground vibrations generated by structure demolition. It is found that the ground vibrations generated by demolition construction will affect the environment and human activities if without any vibration control measures.
