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.
