Abstract
In this paper, the ABAQUS finite element program is used to analyze the influences of the Kushan south railway station reconstruction on the pier, foundation bearing capacity and deformation of the adjacent high speed railway bridge. The results of numerical simulation analysis show that (1) after the completion of the additional Kushan south railway station structures, both the bearing capacity and local stress of the bridge pier of HSR satisfy the requirement of design and standard; ( 2 ) the friction, shear force and bending moment of HSR bridge pile foundation have no obvious change during and after the construction of the building pile foundation, but the axial force increases obviously after the upper load is in place; the bridge pier tends to incline to the new construction areas, but the change of horizontal displacement and vertical settlement of pier are less than 1 mm of the control limit;(3) the cement mixing pile is able to reinforce the foundation, but it's necessary to keep a safe distance between the mixing pile and the pier foundation due to the adverse effect caused by the construction on the bridge foundation.关键词
