During the construction of TBM tunnel, the temperature environment inside the tunnel will deteriorate due to the large amount of heat generated by the rock temperature and the mechanical heating. The temperature control near the TBM excavation face is one of the important factors influencing continuous longdistance excavation. In order to formulate reasonable cooling measures for TBM section construction, the heat transfer theory is adopted to study the temperature distribution law with deadend forced ventilation tunnel. The law is certificated by the test data of work area of TBM inclined shaft #5 in the north section of Hanjiang RiverWeihe River Water Conveyance project. By introducing the concept of enthalpy in air conditioning engineering, the load of artificial cooling of TBM tunnel is determined, and common cooling measures are compared and discussed, so as to determine the cooling measures of TBM tunnel construction. The study results show that: (1) The air temperature in the tunnel is associated with the tunnel wall temperature, ventilation air temperature, ventilation air volume, heat generation power of shield in the tunnel, tunnel circumference, ventilation length, heat transfer coefficient of the sidewall of the air duct and heat transfer coefficient of the sidewall of the tunnel. (2) For the environment of hightemperature and highhumidity near the tunneling face, only artificial refrigeration cooling measure can be used to reduce the temperature.
