Abstract

Earth fissure disasters have caused great troubles to urban construction, especially to underground structures like metro stations and tunnels. Previous researches have shown that the existence of earth fissure will give rise to an amplification effect of dynamic response on the site. Therefore, it is necessary to ascertain the dynamic response characteristics of the underground structure in the earth fissure site. In this paper, the numerical model of a typical earth fissure site was established, and the dynamic response of metro station and tunnel at different distances from the earth fissure was simulated. The results show that as the structure is placed closer to the earth fissure, the dynamic response of the axial force, shear force, bending moment, horizontal displacement, deformation, and soil-structure relative displacement of the section will increase significantly. The furthest influence range of the amplification effect can reach up to about 30 m from the earth fissure. The dynamic response increases steadily from 25 to 10 m and rises rapidly within 10 m. As the intensity of the seismic wave increases, the amplification effect increases, but its influence range is fixed. Therefore, a higher seismic fortification level is required for the underground structure such as metro stations and tunnels in the earth fissure site.
