Displacement Response Analysis of Root Foundation under Earthquake Action
The finite element analysis software ANSYS is used to analyze the seismic time history of a concrete filled steel tube through arch bridge.By changing the length and cross-sectional area of the root,the influence of the root on the maximum displacement of the mid-span,arch roof,pier top and pile top of the arch bridge is analyzed.The results show that within a certain range,increasing the length of the root and increasing the cross-sectional area of the root can effectively reduce the maximum displacement of the arch bridge under earthquake.
