| 摘 要： | 根据国内外人工冻结土体热物理参数的研究成果,针对上海冻结范围内土层分布,给出了上海冻结范围内土层热物理参数表。在缺乏实验条件情况下,采用数值方法进行冻结温度场分析时,可根据实际工程土层含水量大小,对表中所对应的土层数据进行插值求得所需的热物理参数。

| Abstract: | Based on the previous research results of thermophysical parameters of artificial ground freezing soil, a table of thermophysical parameters of artificial ground freezing soil in Shanghai was presented. When experimental conditions were unavailable, the thermophysical parameters of soil in actual engineering could be acquired by interpolation method. It is suggested that determining the water content of the frozen soil and utilizing the provided parameter table is effective in analyzing the temperature field of artificial ground freezing by numerical method. |
