摘要

月球探测2期工程中，需在地球上进行探测器软着陆过程及月面巡视探测的模拟试验，上述试验中月壤特性的模拟至关重要。通过试验研制出了适用于上述试验的Tongji-1（简称TJ-1）模拟月壤。但2期工程中可能需用到近千吨的模拟月壤，由于客观条件限制，难以满足含水率为0%、颗粒级配与目标级配完全吻合的技术要求。为此，开展了含水率及颗粒级配对TJ-1模拟月壤力学性能影响的试验研究。根据TJ-1模拟月壤在不同含水率时的力学试验结果，建立了强度参数与含水率的关系式，建议含水率上限值为3%，并通过TJ-1模拟月壤不同颗粒级配曲线下的力学性能测试，得到了级配变化的许可范围。

Abstract

Tongji-1 (TJ-1) lunar soil simulant has been developed as a substitutive material of lunar mare for the purpose of engineering and scientific research. The moisture content and gradation are significant factors influencing the mechanical properties of TJ-1 lunar soil simulant. Their variation is hardly avoided if TJ-1 lunar simulant is manufactured in large quantities. This paper investigates the effects of moisture content and gradation on the mechanical properties (e.g. strength parameters

deformability) in TJ-1 lunar simulant. A series of mechanical tests were designed and performed for TJ-1 lunar soil simulant at different moisture contents and different gradations. The experimental results demonstrate: the upper limit of the moisture content is 3%; the relationship between strength parameters and moisture content and the acceptable range of gradation are obtained.
