摘　　要：用同一台岩土热物性测试仪,在外界温度相差不明显的条件下,对100 m、120 m单U、双U换热器进行测试。数据表明,不同埋管深度、不同换热器类型的热导率、每延米的排、取热量差异很大。在天津地区换热量的主要因素为水文地质条件,其次影响因素为试验工况、换热孔深度、换热器类型、回填材料及其回填固结时间等。The paper first introduces the same rock and soil thermal physical property tester, under the condition of out- side temperature difference is not obvious, About 100 m and 120 m U single, double U heat exchanger were tested. Data show that different buried depth of pipe, heat exchanger type of thermal conductivity, per linear meter, take heat difference is very big. Secondly, the main factors of heat transfer in tianjin area as the hydrogeologieal conditions, the second influence factors for test modes, heat exchanging hole depth and type of heat exchanger, backfill material and backfilling consolidation time, etc.
