The results obtained are summarized as follows.(1) Small scale experiments on thermal storage were carried out based on a similarity rule, which clarified the relationships between hydraulic head and water velocity, flow rate of discharge water temperature, moisture content and stored heat, hygro-thermal properties of the ground and fluxes, and the positions of the well. The results of the analysis based on the heat and mass transfer gave a good agreement with the measured results, thus the analytical model can be used for practical purposes.(2) The temperature and moisture fields including unsaturated region were measured. An unsaturated moisture flow model formulated based on a moving boundary problem could predict the measured results.(3) Based on the measurements of an existing building and ground, the efficiency of the thermal storage was investigated. An examination of the influence of the several factors such as soil characteristics, non-uniform ground strata revealed that the initial temperature distribution has a significant influence on a short term thermal storage, as expected.(4) An optimal method of thermal storage taking into account the control of the building use side was clarified based on a genetic algorithm.(5) Several problems in ground thermal system were identified and the strategies for practical use were proposed.

所得结果总结如下：(1)基于相似规律进行了小尺度蓄热试验，明确了水头与水流速、排水温度流量、含水率与蓄热、地面湿热性质与通量、井位之间的关系。基于传热传质的分析结果与实测结果吻合较好，说明该分析模型具有一定的实用价值。(2)测量了含非饱和区的温度和湿度场。基于移动边界问题建立的非饱和水分流动模型可以预测实测结果。(3)基于对既有建筑和地面的测量，对蓄热效率进行了研究。对土壤特征、非均匀地层等因素影响的研究表明，初始温度分布对短期储热有显著影响，正如预期的那样。(4)提出了一种考虑建筑使用侧控制的最优蓄热方法。(5)指出了地热系统存在的几个问题，并提出了实际应用的对策。
