桩土效应对弯桥抗震设计的影响

Influence of Pile-Soil Effect on Seismic Design of Curved Bridge

以某匝道桥为例,采用大型有限元软件ANSYS和LS-DYNA,建立了考虑与不考虑桩土相互作用两种模型。对弯桥的反应谱分析做了考虑桩土效应与不考虑桩土效应的定性分析,其主要结论对弯桥的抗震设计具有一定的指导意义。

For a ramp bridge as an example, the finite element software of ANSYS and LS-DYNA are used to establish two models of considering and no considering the interaction of pile and soil. The response spectrum of curved bridge is qualitatively analyzed by considering the pile-soil effect and no considering the pile-soil effect. The main conclusion has certain guiding significance for the seismic design of curved bridge.
