土壤热工性能测试及应用分析

介绍了土壤导热系数在温度为稳态情况下的一种测量方法,通过对两种不同物性岩石导热系数的测量,确定了影响岩石导热系数的因素.减少了测试参量,简化了测试的准备工作和测试装置,是一种简易可行的、适用范围较广的、成本较低的导热系数测量方法,为地下工程设计和施工参数的确定提供了一种新的依据.

Analysis on the Thermal Test and Performance of Soil

This paper presents a kind of method for testing thermal conductivity of soil in steady state,that is,measuring thermal conductivity between two different kinds of petrophysics,and induces reasons of thermal conductivity of soil affected.The method is a simple,feasible,widely-used and low-cost one for testing thermal conductivity due to the reduce in test parameters as well as simplification in preparation for test and test device,which provides the underground work and determination on parameter for construction with a new principle.
