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.
