摘要

建立了折板拱形隧道混凝土结构温度应力非线性分析算法

采用现场材料试验数据

应用该算法对苏州独墅湖隧道60m箱涵节段进行了非线性有限元分析

考虑了混凝土徐变以及开裂后构件刚度降低与温度应力间耦合作用的非线性效应。通过测量隧道箱涵控制断面的预埋传感器

获得了混凝土温度变化与钢筋应变量的实测值。基于混凝土温度变化实测值计算出隧道顶板钢筋应变量

该计算值与现场实测值吻合程度较高。算例表明

本算法可实现折板拱形隧道混凝土结构在温度变化和收缩、徐变等间接荷载作用下的受力与变形的非线性分析

分析结果趋近于结构实际力学状态。

Abstract

This paper proposed a nonlinear analysis algorithm for calculating temperature stress of concrete structure of folded plate arch tunnel.Using this algorithm

a nonlinear analysis was performed on a 60m-length segment of Dushuhu tunnel in Suzhou based on in-situ material tests.The nonlinear effects resulted from concrete creep and the coupling action between concrete cracking and temperature stress were also considered.The in-situ measurements of concrete temperature variation and reinforced bar strain were obtained by the embedded sensors on the control sections of tunnel segments.The results of reinforced bar strain in the middle-span of a top-plate of the segments were computed based on the in-situ measurements of concrete temperature variation

and they agreed well with the testing ones.This case study indicates that the nonlinear analysis of concrete structure of folded plate arch tunnel under the indirect loads

such as temperature variation

shrinkage and creep

can be performed to obtain their stress and deformation states

which will approach closer to the real mechanical states of the structure.
