Analysis on Influence of Newly Built Highway Pile-board Structure Underpassing High-speed Railway Bridge
Based on the highway project in the section from G206 Ruijin urban area to Jinan-Guangzhou Expressway Ruijin south exit underpassing Ganzhou—Rujin—Longyan Railway Mianjiang bridge,the model of pile-board structure and piers on both sides is established by using the Midas GTS NX software for the displacement analysis of pier top for#25 and #26 during the construction stage.The ballastless track model of the high-speed railway bridge is built by ABAQUS software,the influence of the newly built pile-board structure underpassing scheme on the high-speed railway pier and the track structure on the bridge are evaluated.The results show that the impact of the pile-board structure underpassing the high-speed railway bridge on the high-speed railway meets the requirements of operation safety.
