Research on Dynamic Characteristics of Tunnels Under Complex Conditions

Application of immersed tunnels started late in China, and it has complex construction conditions with many factors to be considered. Therefore, it is of great importance to obtain the seismic response of immersed tubes under complex environment conditions. Based on the simplified mechanical model of the waterstop of the tunnel joint. In this paper, the structure for the immersed tunnel was established, the expression of the interaction relationship between the structure and the soil body was analyzed, and the dynamic response properties and stress properties of the tunnel structure were obtained. It was concluded that the top and bottom of the tunnel should be reinforced compared to the waist of the tunnel.
