The Assessment to Environment Influence for Moving Vibration of Subway in a City of China

The subway in a city of China is located in an alluvial plain. There are many universities and residential distribution districts. The vibration influence in corresponding zone of the subway should be made evaluation before construction. Based on the parameters of dynamic soil test, the one-dimensional elastic column is used to simulate for computation of the vertical vibration of the subway site. Considered the nonlinear and pseudo-damping of soil, the ground accelerations calculated are shown in this paper. Finally, according to the results of computation of the vibration response and comparing with the interrelated code authors present the relevant conclusion for environmental assessment for moving vibration of subway in this city.
