Experimental Investigation for Tunnel Thermal Environment

Abstract:

A set of simulation device was built on the head end of tunnel. Experiments on the thermal environment of the tunnel were conducted by adjusting the parameters of the supply air and the supply air distance. Experimental results are presented at different layout of the ventilation duct. The range of supply air is at 0.02 cubic meters per second to 0.06 cubic meters per second and the supply air distance is at 0.7m to 3.5m. Experiment results show that the tunnel temperature may be regulated blow 28°C only using ventilation for the virgin rock temperature near 45°C. Experiment result and theory prediction both is basically consistent. Experiment results have provided a direction for the select of cooling design and strategy.
