考虑桩-土相互作用的三跨连续梁桥地震响应分析
Seismic Response Analysis of a Three-span Continuous Beam Bridge Considering Pile-soil Interaction
摘要
Abstract
Taking a high-speed railway three-span continuous beam bridge as an example,a three-di-mensional finite element model of the bridge-soil-pile system is established using ABAQUS finite element software.Nonlinear spring elements combined with damping elements are used to simulate the pile-soil in-teraction,and nonlinear dynamic time-history analysis is conducted on the finite element model.The effects of three seismic waves and three types of site soil conditions on the structural seismic response are compared.Compared with the calculation model without considering pile-soil interaction,the research re-sults indicate that the influence of pile-soil interaction cannot be ignored,and considering the pile-soil in-teraction will significantly increase the displacement and acceleration of the pier top,and pier base shear force.Different seismic waves and site soil conditions also have a large impact on the analysis results;the softer the soil conditions of the site,the more significant the impact of pile-soil interaction on the seismic response of the bridge.关键词
