摘要
Abstract
The traversing construction under high-speed railway bridge can cause excessive displacement for high-speed railway bridge piers, which may affect the safety of railway. Aiming at the impact of traversing con-struction under high-speed railway bridge, taking Danyang Downtown-Riverside New City Expressway traversing under the Beijing-Shanghai high-speed railway Zhangxiang Bridge as the object, this study conducted a three-dimensional construction simulation with Plaxis geotechnical engineering finite element software. The calculation results were input into the fine-grained model of the ballastless track on the high-speed railway bridge estab-lished by ABAQUS finite element software to evaluate the influence of the pile-plank structure and hollow board beam bridge traversing construction on high-speed railway bridge. Relevant calculation results show that the in-fluence of the pile-plank structure and hollow board beam bridge on high-speed railway meets the requirements of structural protection and operation safety.关键词
