To verify the accuracy of the current method for predicting thermal environments in tunnels, a model experimental device was developed. This experimental device was designed to be able to investigate heat transfer in tunnels and heat conduction in the rock and soil surrounding the tunnel by blowing hot air into a thick pipe made of acrylic plastic. Temperature detectors were placed in various positions along the experimental device. The difference in temperatures measured in the model experiment and those obtained through calculation was about 1°C showing that numerical calculations obtained through the current method satisfy accuracy requirements.
