摘要

基于ABAQUS通用有限元软件与清华岩土热力学模型有限元分析程序（TTS-FEP）

分析能源隧道能量传输过程中的温度应力。建立平面应变算例

分别进行线性弹性、非线性弹性和非线性粘弹塑性分析。计算结果表明:通过瞬态传热计算分析

ABAQUS通用有限元软件与清华岩土热力学模型有限元分析程序计算结果接近。由于环向方向较径向方向受到更大约束作用

计算所得环向应力变化较为明显。将衬砌材料分别设定为线性弹性模型、非线性弹性模型与非线性粘弹塑性模型

所得能源隧道应力计算结果较接近。关于温度应力的计算

3种模型计算所得衬砌与围岩界面处温度应力逐渐减小。

Abstract

Based on ABAQUS and Tsinghua Thermo-soil Model Finite Element Program（TTSFEP）

the thermal stress of the energy tunnel during the process of energy transmission is analyzed. An example of plane strain is established

with the constitutive model of linear elasticity

nonlinear elasticity and nonlinear viscoelasticity been set. The results show that: for transient heat transfer analysis

the calculation results of ABAQUS and TTS-FEP is close. As the hoop direction is more constrained compare to the radial direction

the calculated hoop stress changes are more obvious. The constitutive model of lining is set as the linear elastic model

the nonlinear elastic model and the nonlinear viscoelastic model

and after calculation

the calculated stresses are close to each other. For the calculation of the thermal stress

the thermal stress at the interface between the lining and the surrounding rock is reduced by the three models.
