摘要
较为系统地梳理了国内外学者在黏土岩研究领域所取得的成果,主要包括黏土岩的矿物组成、黏土矿物的微观结构、历史成因及其物理力学性质等四个方面。其中对其物理力学性质的综述涵盖了黏土岩的结构、构造和颜色、黏土岩的密度及可塑性、黏土岩的强度特征、黏土岩的膨胀特性、黏土岩的水理性质和黏土岩的流变性能等六个子项。因近年来将黏土岩作为高放废物地质处置库的潜在围岩,成为学术界研究的热点课题;还专门论述了国内外学者在该领域实施的开拓性工作。在此基础上,对部分研究成果进行了讨论;并提出了继续开展黏土岩区域性成因调查、多类型黏土岩物理力学性质对比研究和黏土岩作为地下工程构筑物潜在围岩的长期服役效能研究等三个前沿课题。
The clay rocks research achievements of the clay rocks in the field of geotechnical engineering was systematically combed,including clay rocks mineral composition and microstructure of clay mineral,historical origin and its physical and mechanical properties and so on,four aspects. The physical and mechanical properties covers six subsystems： the structure of clay rock,and a color and density and plasticity of the clay rock,the strength of the clay rock characteristics,the expansion of the clay rock properties,clay rock of hydraulic properties and the rheological properties of clay rocks etc. In recent years,because of the clay rock as potential of high-level radioactive waste geological disposal repository surrounding rock become academic research hot focus,the pioneering work also specially discussed on the implementation of domestic and foreign scholars in this field. On this basis,parts of the research are discussed,and three frontiers are suggested： regional survey for clay rock in China,multi-type clay as a comparative study on the physical and mechanical properties,and long-term service effectiveness research of clay rocks for the surrounding rock in the underground engineering constructions.
