在处理岩石地基中的传热问题时，传热参数的估计以及渗透率和蓄水系数等水力参数的确定变得非常重要。本文介绍了如何在实验室中测定不同水力条件下岩石的热扩散率，并用两台固有仪器测定了我国不同地点采集的六种岩石的热扩散率。验证了本文提出的实验装置的实用性，测得多种岩石的热扩散系数为0.333×10-6~1.19×10-6m2/S。
When we deal with the heat transfer problems in rock ground, the evaluation of heat transfer parameters becomes important as well as the determination of hydraulic parameters such as the permeability and storage coefficient. This paper presents how to determine the thermal diffusivity of rocks having different hydraulic conditions in a laboratory, and the values of thermal diffusivities with six kinds of rocks collected from different locations in this country were determined by using two inherent apparatuses. The utility of the apparatuses proposed in this paper was confirmed, and the rock thermal diffusivities were 0.333×10-6-1.19×10-6m2/s for many kinds of rocks.
