摘　　要：利用月面原位资源制备建筑结构材料是降低月球基地建设造价的重要手段。在制备模拟月壤的基础上,对辐射烧结硬化模拟月壤的物理和力学性能进行研究。结果表明:以火山渣为原材料,可以通过烘干、除杂、粉碎、筛分等处理来制备模拟月壤;在微观形态、颗粒级配、化学组成、矿物组成等方面,制备的模拟月壤与真实月壤和既有的模拟月壤都具有较好的相似性;通过辐射烧结实现模拟月壤硬化,研究烧结温度和模拟月壤颗粒级配对硬化月壤表观密度、烧结收缩率和质量损失率的影响;通过单轴压缩试验明确了硬化模拟月壤的力学性能;烧结温度和模拟月壤颗粒级配对烧结硬化月壤的力学性能有显著影响;在单轴压缩试验破坏前,试件没有发生明显塑性变形,弹性模量无明显变化,近似理想线弹性材料。The use of in-situ lunar resources to prepare structural materials is an important method in reducing the construction cost of lunar bases.On the basis of preparing simulated lunar regolith,the physical and mechanical properties of radiation sintering hardened simulated lunar regolith were studied.The results indicate that using volcanic slag as raw material,the preparation of simulated lunar regolith can be achieved through processes such as drying,impurity removal,crushing,and screening.The prepared simulated lunar regolith shows good similarity with the real lunar regolith and existing simulated lunar regolith in terms of microstructure,particle size distribution,chemical composition,mineral composition,etc.Simulated lunar regolith hardening was realized through radiation sintering,and the effects of sintering temperature and particle size distribution on the apparent density,sintering shrinkage,and mass loss rate of hardened lunar regolith were studied.The mechanical properties of hardened simulated lunar regolith were determined through monotonic compression tests,and the sintering temperature and particle size distribution of simulated lunar regolith had a significant impact on mechanical properties.Before the monotonic compression failure,the specimen did not undergo significant plastic deformation.The elastic modulus did not change significantly,demonstrating the perfect linear elasticity.
