某曲线连续梁桥横向偏位成因分析及处置方法

Causes Analysis and Disposal Methods of Continuous Horizontal Curve of a Bridge of Deviation

通过对万安大桥引桥横向偏位病害现状及发展趋势分析，初步探讨了在温度变化，混凝土收缩徐变，汽车荷载作用下6牡蛘墩问粱体产生横向偏位的机理，在此基础上提出针对其横向偏位的处治方法。0引胃曲线连续梁桥是一种在大型公路立交桥和城市立交桥中应用较多的桥型，但是一直以来，由于对温度变化，混凝土收缩徐变，汽车荷载等产生的效应认识不足，致使曲线梁桥产生横向偏位。本文就万安大桥引桥产生的横向偏位的实例进行分析，并介绍采取的处理措施。

Abstract This paper analyzes deviation of disease status and development trend of Wan＇an Bridge approach, a preliminary study of the temperature changes, shrinkage and creep of concrete, car loads, 6 #-9 # pier between the transverse beam deviation mech- anism, in this based on the lateral doviation of for its treatment method.
