连续梁支座错误摆放对桥梁下部结构影响分析

Influence Analysis of Continuous Beam Bearing Error Placement on Bridge Substructure

运用计算机有限元技术,模拟分析了连续梁边墩纵向支座横向错误放置,在气温上升和下降时,梁部伸缩对桥墩下部结构的内力影响,指出了潜在危害,为桥梁施工提供教育警示作用,为桥梁养护提供了指导作用.

By using finite element computer technology,this paper simulated and analyzed the misplacement of continuous beam side-pier bearing from longitudinal direction to transverse one,and the influence of beam expansion on the bridge substructure.Then,it pointed out the potential hazards.It could provide education warning for bridge construction,and serve a guiding effect for bridge maintenance.
