变形、渗流、热、化学反应耦合作用下，矿体孔隙、裂隙、矿物组构等细观结构发展变化，与宏观渗流力学特性、固体力学特性的实时演变相关规律是流体力学、岩体力学与资源开采领域的重要研究课题，也是国内外刚刚涉猎的前沿课题。本项目拟以油页岩矿体为代表，开展相关研究。.拟定在20-600℃范围内，5-30MPa轴压与围压组合的三轴应力下，5-15MPa渗透压作用下，采用我校刚研制的CT-THMC耦合实验系统，宏细观在线实时同步研究油页岩孔隙裂隙演变规律、宏观固体力学特性、渗流力学特性、以及与细观孔隙裂隙的相关规律。复杂的THMC耦合作用，宏观固体与渗流力学特性与细观孔隙裂隙同步在线试验，剧烈化学反应的矿岩样，是本项目显著特色与创新。.本项研究为油页岩原位开采提供技术支持。拓展力学学科的内涵，深入、丰富与发展岩体力学、渗流力学、宏细观力学与多孔介质传输理论。

On the coupling effects of deformation, seepage, thermal and chemical reaction, the microstructure evolution of ore body pores and cracks, the constitutions of mineral, along with the real-time evolution of macroscopic seepage mechanics, solid mechanics, are not only the significant research area in the fields of fluid mechanics, rock mechanics and resource exploitation, but also the latest domestic and overseas research frontier. ..In this project, the body of oil shales would be used to carry out related research. In the range of 20-600℃, 5-30MPa triaxial stress of axial compression combined with confining pressure and 5-15MPa osmotic pressure, the newly developed CT-THMC coupling experiment system would be used to online synchro-study the evolution of pores and cracks of oil shales, macroscopic solid mechanics, seepage mechanics and related evolution laws of microscopic pores and cracks. Complex THMC coupling effects, the synchronous online test of macroscopic solid, seepage mechanics with microscopic pores and cracks, violent chemical reaction mineral samples, are the remarkable feature and innovation points of this project. ..This project would provide technical supports for oil shale in-situ exploitation. It would also expand the connotation of mechanics, deepen the rock mechanics, enrich seepage mechanics, and develop mechanics of macroscopic and microscopic and porous media transmission theory.
