Description
Summary:Based on finite element software ABAQUS, by using equivalent viscous-spring artificial boundary element combine wave motion input, a series of two-dimensional plane strain models of above building-soil-tunnel were built to study the influence of above building on tunnel dynamic response. The dynamic nonlinear effects of soils are considered by using equivalent linear method. Three seismic input with different spectrum characteristics were used here as input motion. Results show that the influence of above building is negligible. The dimension of above building, spacing between structures and the buried depth of tunnel are the important factors of the interaction system, in contrast, the stiffness of above building have small influence degree.
