基于正交试验和灰色关联的黏土热学性质研究

Research on Clay Thermal Properties Based on Orthogonal Test and Grey Correlation

文中主要研究含水率、干密度和固结压力三种影响因素对黏土导热性能的影响。通过对黏土热扩散系数进行极差分析和灰色关联分析,结果表明:两种分析的结果基本一致,干密度是影响黏土热扩散系数的主要敏感因素,含水率和固结压力的敏感性次之。通过两种分析方法相结合,定量分析各影响因素间的主次关系,达到对研究对象各影响因素整体评价的目的。

This article mainly studies the influence of three influencing factors,moisture content,dry density and consolidation pressure on the thermal conductivity of clay.Through the range analysis and gray correlation analysis of the thermal diffusion coefficient of clay,the results show that the results of the two analyses are basically the same.Dry density is the main sensitive factor affecting the thermal diffusion coefficient of clay,followed by the sensitivity of water content and consolidation pressure..Through the combination of two analysis methods,quantitative analysis of the primary and secondary relationship between the various influencing factors,to achieve the purpose of overall evaluation of the various influencing factors of the research object.
