文章简要介绍Probert和Claesson针对瑞典KBS-3V高放废物处置概念库开展的温度场解析求解方法研究，包括全域解和局域解。全域解将处置库区域内规则排列在网格单元上的废物罐热源简化为无限大平面热源得到，局域解由无限多平行巷道排列的线热源、无限大平面上网格点热源，及沿废物罐高度方向上的有限长线热源产生。最终所有附加场叠加在处置库原始温度场得到总温度场。应用解析法计算处置库温度场与用数值法计算温度场相比，得到的表达式简洁，物理意义明确，计算时间更快，适用的处置时间更长。最后，提出了开展中国高放废物处置概念库温度场解析求解的研究思路。

Method study of the analytical solution to the temperature field in KBS-3V HLW repository in Sweden by Probert and Claesson is introduced. The solution consists of global temperature field and the local one. The grid points within the repository are simplified as the heat source distribution to a rectangular plane heat source for global solution. Local solution consists of a line heat source, an infinite rectangular grid of point sources and a balancing plane sink. The total temperature is the sum of the global temperature, the local temperature and the undisturbed rock temperature. The analytical approach gains simple formulas and physical understanding. It is valid to longer repository time and shorter calculating time compared with numerical approach. The approach of analytical solution to temperature field in HLW concept repository is proposed in the end.
