Abstract:	用過核燃料的最終處置方式，必須對環境與生物造成無害。經過國際間評估與研究，深地層處置(deep geologic disposal)被認為是最安全可行的處理措施。本研究以有限元素軟體ABAQUS進行完全耦合熱-水-力學之分析。處置場分析研究以深地層處置之概念為基礎，參考日本及瑞典相關文獻，考慮熱源、緩衝材料、回填材料、母岩之熱與水力特性進行分析並對照各國文獻之結果。處置場內核廢料之間距尺寸分析採用台灣電力公司之探勘數據及其規劃之處置場尺寸，及考量國內文獻對處置場尺寸及材料特性，並研究處置孔不同間距尺寸與不同熱傳參數對於處置場之溫度及飽和度影響。針對處置場內有開挖擾動帶及裂隙探討對處置場內之溫度場及飽和度場之影響。 ;Final disposal of spent nuclear fuel waste must be harmless to the environment and biological. After the international evaluation and research, deep geological disposal is considered the most safe and effective treatment measures. In this study, using the finite element software ABAQUS to analysis fully coupled thermal-hydro-mechanical calculation of final nuclear fuel waste repository. Disposal site analysis of the conception bases on deep geological disposal. Considering the spent nuclear fuel waste, buffer materials, backfill material and rock material thermal and hydraulic characteristics of for analysis and comparison of the results of the literature countries. The distance of deposition holes and disposal field size analysis using the Taiwan Power Company′s exploration data, and considering domestic literature of the size of disposal site and material properties, and to study different deposition holes distance different size and heat transfer parameters for disposal influence of temperature and saturation. Consider the influences of excavation damage zone and fracture in disposal site and discussion the temperature field and the saturation field.
