Tunnel structures in civil engineering used as heat exchange components for shallow geothermal are named "energy tunnel". In shield tunnels, heat exchange tubes are installed in the prefabricated segments to form "tunnel energy segment" (TES), TESs are connected to form a circuit in site. This type of tunnel is called "energy shield tunnel". Based on two examples of energy shield tunnels abroad, construction methods of geothermalutilized shield tunnels such as the prefabrication of energy segments and the onsite installation of segments have been summarized combined with the design, fabrication and installation of 27 TES of Qinghuayuan Tunnel in BeijingZhangjiakou Railway. According to the specific problems encountered in the construction, possible solutions are given for the problems faced by largescale construction of TESs from the perspectives of tube production and onsite construction.
