摘　　要：通过对埋深约250m的北京SSL地下水电站交通洞换热特性5d的连续现场实时监测,分析了洞内空气温度随距洞口距离的变化规律及交通洞的节能潜力,测试结果表明地下交通洞对送风空气有明显的降温和升温效果。测试发现夏天1000m温降最大约达6℃,温升近3℃;每km最大供冷能力可达380kW以上,供热能力达140kW以上,且在交通洞末端靠近主厂房处温度维持在约23℃,北京SSL水电站利用地下隧洞节能潜力巨大,在夏季及冬季可以部分或全部替代空调冷热源,具有显著节能意义。By the field test on heat exchange in tunnel, the deapth is about 250m, of SSL underground hydropower station for 5 days, the change regulation of temperature was analyzed by tunnel inlet distance. It was presented that the tunnel has a significant influence on the temperature-decline and temtyerature-raise of supplied wind. In summer, the temperature decline can reach 6℃/kin, while temperature raise can be 3℃/km; Under this situation, the utmost cooling capacity can be 380kW/km, while heating capacity more than 140kW/km; In the end of tunnel close to the main plant, the tem- perature maintain about 23 ℃, By utilizing the energy saving function of underground tunnel, the potential is immense. Air conditioning heat source and heat sink can partially or even totally be replaced by the underground tunnel in summer and winter, thus remarkable energy saving can be arrived.
