| Abstract: | In order to research double-column highway bridge with high piers in southwest mountain area,the spatial dynamic model considering the coupling of bearings,superstructures and substructures was established.The effects of some structural parameters on bridge seismic responses were studied in detail respectively.These parameters include height of piers,pile-soil interaction,single-segment and multi-segments models,single-segment model with different span numbers,single-segment and single-pier model,and terrai... |
