摘要： 为解决寒区隧道冻害问题，将地源热泵型供热系统应用于内蒙古博牙高速扎敦河隧道中。将热交换管以串联纵向的布置形式埋设在初衬与二衬之间，隧道衬砌施工过程中的水化热影响围岩的温度场，从而影响热交换管的换热量。研究表明：隧道施工过程中，衬砌水化热对围岩温度场产生两次影响；保温层可以加剧水化热的影响，浅部围岩温度场受到的影响更显著；衬砌水化热提升热交换管的换热量，保温层铺设越早，热交换管换热量提升也越大，最大达到31.9%。系统运行初期，应充分利用衬砌水化热对热交换管换热产生的有利影响。

Abstract: In order to prevent the freezing damage of tunnels in cold regions, the heating system with ground source heat pump was applied at Zhadunhe Tunnel of Boya Highway in Inner Mongolia Autonomous Region of China. Heat exchange pipes were buried between the initial lining and the secondary lining in series arrangement of vertical. Hydration heat induced by lining construction in tunnels influenced the temperature field of surrounding rock, and then influenced the heat transfer rate of heat exchange pipes. Research results show that: during the construction of tunnel, the temperature field of the surrounding rock is affected twice by lining hydration heat; the thermal insulation layer aggravates the influence of hydration heat, and the temperature field of shallow rock is more significantly affected; the hydration heat of lining construction can increase the heat transfer rate of heat exchange pipes; the sooner thermal insulation layer lay is established, the greater heat transfer rate of heat exchange pipes is increased, and the maximum reaches 31.9%. At the beginning of system operation, the favorable impact of hydration heat induced by lining construction should be made full use in the process of heat transfer rate of heat exchange pipes.

Key words: tunnel engineering, ground source heat pump, heat exchange pipe, hydration heat;heat transfer rate
