摘要

首先探讨了黄土导热系数和比热容的测试方法，组装形成黄土土样试验装置。然后取扰动黄土配制不同密度、不同含水量试样进行试验，测得黄土导热系数和比热容。实验结果揭示出，在含水量一定的情况下，导热系数和比热容随密度增大而增大；在密度相同的情况下，导热系数和比热容亦随含水量的增大而增大。进一步分析得到根据土体含水量、密度确定导热系数和比热容的关系式。相对于随密度的变化，黄土导热系数和比热容随含水量的变化尤为显著，含水量变化可以引起热参数较大的变化。

Abstract

Experimentation for coefficient of thermal conductivity and specific volume heat of loess is explored first; and the experimental installation is installed. Then taking loess samples with different densities and moisture contents

the coefficient of thermal conductivity and specific volume heat of loess are tested. The test data show that for loess with constant water content

if the density is increased

the coefficient of thermal conductivity and specific volume heat both are increased. And for loess with constant density

if the water content is increased

the coefficient of thermal conductivity and specific volume heat both are increased too. Based on research on the test data

two formulas are obtained to determine the coefficient of thermal conductivity and specific volume heat of loess. After that it is pointed out that compared with soil density changes

water content change can result in more variations of coefficient of thermal conductivity and specific volume heat of loess.
