粘土岩物理力学及工程特性研究综述

本文较为系统的梳理了国内外学者在粘土岩研究领域所取得的成果,主要包括粘土岩的矿物组成、粘土矿物的微观结构、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粘土岩的结构、构造和颜色、粘土岩的密度及可塑性、粘土岩的强度特征、粘土岩的膨胀特性、粘土岩的水理性质和粘土岩的流变性能等六个子项。因近年来将粘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,本文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,本文对部分研究成果进行了讨论,并提出了继续开展粘土岩区域性成因调查、多类型粘土岩物理力学性质对比研究和粘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。

Review of the Physical, Mechanical and Engineering Properties of Clay Rocks

This paper systematically combed the clay rocks research achievements of the clay rocks in the field of geotechnical engineering, 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 of this paper 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, this paper also specially discusses the pioneering work on the implementation of domestic and foreign scholars in this field. On this basis, in this paper, 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.
