摘　　要：寒区隧道地源热泵型防冻保暖系统由取热段、热泵和加热段三个部分组成。在Adam研究能源土工布热交换器中热交换管布置形式的基础上,考虑了寒区隧道热交换管的抗冻性,对热交换管布置形式进行了优化评估分析,得出串联横向布置形式是寒区隧道热交换管的最佳布置形式。对热交换管的布置位置进行了优化分析,包括轴向和环向两方面,得出热交换管的轴向最佳布置位置为每板二衬内,不宜跨板布置,环向最佳布置位置为高于环向预埋件。系统首次应用于内蒙古林场隧道,结合试验段开展进行了热交换管的施工关键技术、施工质量控制和施工后期保护的研究,为林场隧道顺利实施提供理论依据和技术支持,并为今后类似工程的施工提供宝贵的经验。In tunnels of cold regions the anti-freezing thermal system of ground source heat pump consists of heat getting section , a heat pump and heating section. Adam has studied the arrangement of heat exchanger tubes in energy geo-composites. On the basis of the study result and considering the frost resistance of the tube, an optimization assessment analysis of lining heat exchanger tubes has been done and it showed that the horizontal arrangement in series is the optimal arrangement. The laying position of heat exchanger tubes has been studied at both the axial and the circumferential position and it showed that the best axial laying position of heat exchanger tubes was in each secondary lining and the best circumferential laying position of heat exchanger tubes was at the place higher than the embedded parts. This system has been first used in Linchang tunnel of Inner Mongolia. Construction technologies, construction quality control and post-construction protection of lining heat exchanger tubes have been studied in the test section, providing theoretical bases and technical support for Linchang tunnel and also providing valuable experience for the future construction of similar projects.
