摘　　要：正交试验设计是安排多因素试验的一种科学方法,灰色关联度法可以分析各因素各水平对正交试验结果影响的主次关系.本文用灰关联度分析法对室内正交冻胀试验结果进行分析,得出长春季冻区土的压实度,含水量及冻结温度对冻胀量影响大小的排序,结果表明,土的含水量与冻胀量的关联度最大,与压实度的关联度次之,与温度的关联度最小。Orthogonal trial is one of scientific approaches to many elements tests, We could get principal or secondary relations of results of orthogonal trials of every factor and every level by use grey relation analysis （GRA） method . In this paper, GRA is used to analysis results of orthogonal heave tests indoor, we get sequencings of compactness of soil, water content and freezing temperature according to contribution to heaving susceptibility. The results indicate that water content of soil has max correlation degree to heaving sus- ceptibility, compactness takes second place and temperature is the lowest.
