Review of Engineering Geological Characteristics of lunar regolith

摘要:

根据国内外的最新研究成果，综述了近年来月壤工程地质力学特性研究的新进展。首先简述了月壤的矿物特征与化学成分，分析了月壤的级配、颗粒形态与孔隙率等物理性质对月壤性质的影响；然后介绍了月壤的变形特性与强度特征，阐述了目前模拟月壤的主要类别，及其内摩擦角、弹性参数等力学参数的研究成果；最后指出月壤研究中存在的问题，即模拟月壤试验必须注意环境变量（如弱重力）及化学成分对于工程地质性质的影响，同时应加强对月壤动力性质方面的研究。

Abstract:

Some recent advances of engineering geological properties of lunar regolith are summarized in the aspect of the influence of specific environment on the lunar regolith properties. Firstly, the geochemical characteristics of the lunar regolith researches are outlined briefly, including mineral characteristics and chemical composition. The influences of lunar regolith size distribution, particle shape and porosity on lunar regolith properties are analyzed. Then, the mechanical properties of the lunar regolith are introduced, including the deformation characteristics and strength characteristics. The main types of lunar regolith simulation are presented, and so do mechanic parameters of the stimulation soil, such as the angle of internal friction and elastic parameters. Lastly the existing problems in the lunar regolith research are pointed out that the effects of environment variables (e.g. the weak gravity) and chemical composition for the engineering geological behavior should be taken into account in simulant test and the dynamic nature of lunar regolith also should be paid more attention.
