Abstract：
Analyses the mechanisms of dymanic heat transfer in the underground works envelope, and presents the simplified calculation method for heat transfer. With the cooperative function of MATLAB, Simulink and COMSOL, simulates the dynamic variation of the heat load, and validates the simulation results by an experiment.
