Simulation Analysis of the Entire Process of the Main Bridge Incremental Construction of Luoxizhou Bridge
There are few cases of design and construction of large span open K-shaped steel trusses,and the difficulty of incremental launching construction is relatively high.In the paper the key technologies of the large-span and long connected open K-type steel truss launching construction are studied based on the Luoxizhou Bridge project.The whole process of the incremental launching construction is simulated and analyzed using the finite element software Midas Civil,and the strength of the steel truss and guide beam are checked.The launching force under various working conditions is calculated,and the strength of the temporary pier is checked.The research results indicate that the steel truss,guide beam,and temporary pier can meet the structural stress requirements during the jacking construction process,and the use of finite element method can effectively predict the magnitude of the jacking force of the foundation and temporary pier during the jacking construction.
