摘要
为了给人工冻土水热力耦合数学模型的建立提供可靠的依据,安徽理工大学冻土所根据相似原理设计并进行了人工冻土多圈管冻结模型试验。本文在模型实验的基础上,在温度方面对多圈管冻结土体进行了深入全面的研究,并且得到了冻结温度随冻结时间的变化规律,对矿井的工程实际具有重要的指导意义。
In order to establish reliable the mathematial model of artificial frozen soil heat _ moisture _ stress _ coupling, The Forzen Soil Institute of Anhui University of Science and Technol-ogy design and make multi - coil pipes model experiment based on the principle of similar. The paper make an in _ depth com-prehensive study in terms of temperature of frozen soil. The varia-tions of the temperature filed againt the freeing time are ob-tained. The results can be used in mining engineering practice.
