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 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.. © 2024 Editorial Board of Jilin University.
