Key technology and force analysis of 1-80 m simple supported arch arch rib assembly construction
As one of the common structures in Bridges,simple supported arch has the advantages of high compressive bearing capacity,good flexibility,good dynamic stability,short construction period,etc.,and its arch rib assembly stage is related to the construction safety of the whole project.Based on the Weifang-Yantai railway project,this paper expounds the overall lifting scheme of a simple branch arch and the key technologies in the construction process,and carries out the calculation,analysis and stability calculation of the construction process.The results show that the strength and stress checking of the simple arch rib meet the requirements,and the structure size and checking content can provide reference for similar projects.
