我国红黏土物理力学性能研究现状及展望

采用文献综述研究方法,梳理了红黏土研究成果并进行了评述,对红黏土的物理力学性质进行了归纳和总结,对红黏土的性能改良研究成果进行了汇总,指出红黏土的物理力学性能的差异性根源在于微观结构的个性差异存在,红黏土性能改良的困难在于红黏土的水敏性和热敏性,红黏土性能改良的关键在于控制其含水率。最后指出了研究不足在于普适性理论和知识体系没有构建,改良方法和技术探究应该加强,展望了红黏土性能改良的物理—化学—生物耦合作用的机理及复合技术开发和应用的研究。

Current Research and Prospect on Physical and Mechanical Properties of Red Clay in China

Current research of red clay is summarized and commented by literature review.The physical and mechanical properties,as well as the performance improvement of red clay are summarized.The difference in the physical and mechanical properties of red clay is due to the individual differences in microstructure.The difficulty in improving the performance of red clay lies in the water sensitivity and heat sensitivity,and the key to improving the performance is to control its moisture content.The research deficiency is that the general adoptability theory and the knowledge system are not established,and the improvement methods and technical exploration should be strengthened.Research on the mechanism of physical—chemical—biological coupling of red clay performance improvement,and the development as well as the application of composite technology are prospected.
