随着人类探月工程的快速发展,月球基地建设以及月表资源开发利用有望更快实现,合理预测月壤工程力学性质对于未来深层次探月工程意义重大,我国嫦娥五号返回月球样品为研究月壤工程力学特性提供了直接的实测材料。然而,月球样品极其珍贵,难以满足传统土工试验测试.为了应对这一科学挑战,本研究从无损分析月球样品颗粒属性入手,使用高精度X-射线μCT扫描、三维白光干涉、原子力显微镜等无损测试手段,分析了不同类型月壤颗粒的三维多尺度形态、弹性力学和摩擦属性等指标.在此基础上,基于颗粒材料宏微观物理力学理论和数值模型尝试预测了嫦娥五号采样处月壤残余内摩擦角。本研究为基于月球样品信息跨尺度分析月壤工程力学性质提供了可行思路。
