Method and system for determining temperature comfort zone range in tunnel by considering altitude and ground temperature

The invention discloses a method for determining a temperature comfort zone range in a tunnel considering altitude and ground temperature, and relates to the technical field of tunnel engineering blasting construction, the method comprises the following steps: according to model parameters, environmental parameters and design specifications, obtaining design required air volumes under different conditions and different altitudes; according to the model parameters, the environment parameters and the design required air volume under different conditions and different altitudes, the air pipe air speed required by ventilation and the air supply temperature under different altitudes are obtained; according to the air pipe air speed needed by ventilation and the air supply temperatures at different altitudes, the ground temperature unchanged altitude change and the change of a temperature field in the tunnel when the altitude is unchanged and the ground temperature change are obtained; according to the change of th
