摘　　要：阐述了高速公路梁式桥病害产生的原因,分析了温度裂缝、荷载裂缝产生的原因,并建立模型利用有限元分析讨论温度梯度、荷载对桥梁上部结构裂缝的影响.This paper expounds the causes of cracks in the superstructure of beam bridge on expressway and analyzes the causes of temperature crack and load crack.A bridge model is established based on midas civil,a finite element analysis software,which makes a selective analysis on the influence of cracks affected by temperature gradient and load in superstructure of beam bridge.

关 键 词：高速公路 桥梁 裂缝 有限元分析
