Controlling the ambient temperature inside a tunnel to less than 28 °C is the key to ensure safe operation of tunnels that experience high-geothermal temperature. One of the most popular methods to lower the ambient temperature of an extra-long tunnel with high-geothermal temperature is mechanical v...
