摘要
Abstract
Based on bearing replacement of bridge,the finite element sofeware Dr.Bridge V3.2.0 was applied to calculate jacking up of bearing replacement influence on the structural peformance of variational continuous beams to ensure security of structure. The analysis results show that the section stress increment of beam body and bearing displacement of jacking up pesents a approximate linear relationship,the forced displacement of 10 mm has little influence on beam body and the largest increment was 5.9% ,forced displacement of 10 mm can be taken as limit height connidering the beam body safety.关键词
