深部岩体传热机理的研究现状与进展

基于国内外深部工程普遍面临的高温状况，探讨了深部高温的形成机制与影响因素。围绕岩体导热性质研究、水热耦合迁移问题和工程环境对传热的影响三个方面阐述了深部岩体传热机理的研究现状，目前的研究成果主要体现在建立了深部工程的热交换理论体系、矿山地热学的理论体系和地下工程制冷降温系统的热力学基础。在总结分析的基础上，确立了深部岩体流固耦合传热问题的研究思路：开展深部工程区域的的渗流场监测和开展岩体的流固耦合传热实验和建立岩体在应力-渗流-温度耦合条件下的传热模型，揭示深部岩体的传热机理。

Current situation and Advance of Heat-transfer Mechanism in Deep Rock Mass

Based on the high temperature condition in deep engineering, the formation mechanism of the deep high temperature and influencing factors are discussed. The situation of the research of heat transfer mechanism in deep rocks is expounded from thermal properties of rock mass ,water heat coupling transfer and engineering environment effect on the heat transfer. The present Research results mainly show that heat exchange theory system of deep engineering, mining geothermal theory system and thermodynamics basis of refrigeration cooling system in underground engineering have been built. On the basis of the analysis, the research ideas of flow-solid coupling heat-transfer of deep rock mass are confirmed,including seepage field monitoring of deep engineering, fluid-solid coupling heat-transfer experiment and stress-seepage-temperature coupling heat-transfer model. Through these ,the heat-transfer mechanism of deep rocks is revealed.
