中文摘要：

为分析人工冻土单轴抗压强度影响因素敏感性，选定人工冻土单轴抗压强度的7种影响因素，按正交试验设计方案进行大量冻土单轴压缩试验，并采用灰色关联理论对试验结果进行分析，研究分析诸因素敏感性排列顺序．试验结果表明：在选定的7种影响因素中，温度为最大敏感因素，其它依次为深度、土性、养护时间、加载速率、含水率和密度，且选定的7种因素均为重要影响因素，为相关室内试验与工程应用提供依据．

英文摘要：

In order to analyse the sensitivity of the influential factors of the uniaxial compressive strength of the artificially frozen soil, this paper selected seven influential factors of the uniaxial compressive strength of the artificially frozen soil, according to the method of orthogonal experiment design, a number of uniaxial compression tests are conducted, the test results are analysed by using the grey relational theory, the magnitude of the sensitivity of all selected influencing factors and the order of arrangement of them are given. The results show that： In the selected seven influential factors, the temperature is the most sensitive influencing factor, and then is the depth, the next is soil property, followed by loading rate, maintenance time and density, and the selected seven influencing factors are all important factors, provided the basis for related laboratory test and engineering application.
