The Impact of Steel Frame Bridge Construction on Underpass Tunnels
In view of the construction of the steel frame bridge,it often has a certain impact on its underpass tunnel.This paper uses the finite element software Midas GTS NX to establish a three-dimensional model to study the impact of steel frame construction on the lower tunnel.The results of the study found that the steel frame with friction pile foundation was mainly based on the vertical settlement of the tunnel caused by the construction process,and the closer the distance of the pile base distance,the more obvious the deformation of the tunnel structure;the steel frame pile during the construction of the base and the upper structure,the level of lining and vertical convergence will cause the vertical convergence value of the lining.The characteristics of gradually decreased,resistance of the side motorcycles is the characteristics of gradually increasing,which is consistent with the working mechanism of the actual medium friction pile.
