At present,BIM technology is more and more widely used in bridge construction.This technology can simulate the bridge construction process,mechanical positioning and on-site collision situations,and provide computer simulation analysis for subsequent construction.Meichi Bridge in Diankou,Zhuji,Zhejiang is a through steel arch bridge with a main span of 188 m.The BIM technology is used to simulate the construction process,which can provide a preview for the subsequent on-site construction.The construction is carried out in strict accordance with the simulation process,and good results have been achieved.
