This invention relates to the field of physical similarity simulation technology, specifically providing a physical simulation method for the formation process of lunar lava tube structures. The method involves preparing a simulated melt that meets the rheological and thermodynamic similarity criteria of basaltic lava by mixing thermoplastic materials with condensation additives.
