Abstract

Abstract: The method of observing the deformation of Heyang Jialing River concrete-filled steel tube arch bridge is introduced.The differences between theoretical and measured deformation of the bridge and the causes of differences are analyzed.Furthermore,it is pointed that the deformation of long-span concrete-filled steel tube arch bridge operating many years has complex space state;and the state of deformation often can't be accurately forecasted.

Key words: CFST (Concrete-Filled Steel Tube), arch bridge, deformation, temperature, finite element

摘要： 介绍了合阳嘉陵江大桥钢管混凝土拱桥变形观测方法,分析了该桥实测变形及理论温差计算变形之间差异及造成差异的原因,并指出运营多年大跨径钢管混凝土拱桥变形复杂的空间状态,其变形状态往往是不可准确预测。
