摘　　要：在月球南极永久阴影区内探测水冰物质是我国嫦娥七号的重要任务,为此在地球环境下开展模拟研究,制备极区含水模拟月壤测试样本,并对其月壤模拟物进行超低温条件下的力学特性测试,分析含水率、相对密实度、温度、加载速率及基材配比与抗压强度变化规律。结果明:冻结月壤模拟物的抗压强度随着含水率的增加而增大,随着密实度的增加而增大,随温度降低而增大,受加载速率变化的影响较小,受不同基材配比影响的抗压强度排序为:100%斜长岩<90%斜长岩+10%玄武岩<70%斜长岩+30%玄武岩<100%玄武岩月壤模拟物。最后,通过灰色关联分析探究月壤模拟物含水率、相对密实度、温度、加载速率、配比等基本物理性质指标与抗压强度的关联度,关联度排序为:含水率>密实度>温度>配比>加载速率。本文进行了含水月壤制备及力学特性测试,提出了更加系统规范的实施方案,作为极区含水月壤特性的研究基础,为后续月壤模拟研究提供了理论依据及参考。The primary objective of the Chang'e-7 mission is to detect water ice in the permanently shadowed regions of the Moon's south pole.This study involves conducting simulation research within an Earth-based environment,preparing test samples of polar hydrous simulated lunar soil,and assessing the mechanical properties of these simulants under ultra-low temperatures.Additionally,it analyzes how various factors—including moisture content,compactness,temperature,loading rate,substrate composition,and compressive strength—interact.The results indicate that the compressive strength of the frozen lunar soil simulants increases with higher moisture content,greater compactness,and lower temperatures,while it is less influenced by variations in loading rate.The compressive strength is affected by substrate composition in the following order:100%plagioclase<90%plagioclase+10%basaltic<70%plagioclase+30%basaltic<100%basaltic lunar soil simulant.Furthermore,this study employs grey correlation analysis to explore the relationships among fundamental physical property indices such as moisture content,compactness,temperature,loading rate,substrate ratio,and compressive strength.The analysis reveals the following order of correlation strength:moisture content>compactness>temperature>substrate ratio>loading rate.This paper not only examines the preparation and mechanical properties of aqueous lunar soil but also proposes a more systematic and standardized implementation scheme.This serves as a foundational basis for understanding the characteristics of polar aqueous lunar soil,providing valuable theoretical insights and references for subsequent lunar soil simulation research..
