摘要

摘要: 月壤原位成型技术作为月球资源原位利用技术体系中的研究热点，是在月表制造建筑材料及实施月表基础设施建设的关键。基于国内外月壤原位成型技术发展现状，采用放电等离子烧结技术（SPS）实现了模拟月壤的成型，并通过准静态压缩试验研究其抗压强度和弹性模量。最后以石拱桥结构和榫卯结构的建造理念，进行了月球基地结构体系的设计，提出了构件连接方式，并通过有限元模拟分析了拱形结构对于建造月壤成型结构的适用性，提供月壤原位建造的可行路径。

Abstract: As a research hotspot of in-situ utlization techniques for lunar resources, the in-situ forming technique of the lunar soil is the key to the manufacture of construction materials and the implementation of the lunar surface infrastructure. Based on the development status of in-situ lunar soil molding technique, spark plasma sintering (SPS) was used to achieve the modeling of simulated lunar soil. A quasi-static compression test was conducted on the molded specimen to study its compressive strength and elastic modulus. Based on the construction concept of the stone arch bridge structure and tenon structure, the lunar base structure system was designed, and the component connection method was proposed. Moreover, the applicability of arch structure to the construction of lunar soil molding structure was analyzed by finite element simulation. The results could provide a feasible path to achieve the in-situ construction by the lunar soil.
