高速铁路连续箱梁支座纵向预偏量理论数值精确计算研究OA

The high-speed intercity railway crosses the Urban area,spans roads and rivers,and has many continuous box girder structures.Continuous box girder bearings require high installation accuracy and difficult control.Among them,there is no detailed description in design reference documents or specifications for the calculation of bearing pre-deflection,and there is a high possibility of errors during the actual calculation process.This paper conducts sufficient and detailed research and analysis on the theoretical numerical accurate calculation of the bearing pre-deflection of continuous box girder of high-speed railway,and forms a concise and accurate algorithm,which can be used as reference for subsequent projects.
