|Lunar lava tubes are unique geological structures on Moon that are formed due to the cooling of the surface magma. These structures are the excellent candidates that have the potential of shielding astronauts from lunar radiation and impacts. To safely host the astronauts in these caves, it is necessary to analyse the stability of the lava tubes. Terrestrial construction of tunnels is the inspiration and backbone of the analysis presented in this report. The famous Hoek-Brown failure criterion has been used to analyse the rock mass properties of these lunar lava tubes. An attempt to determine the radius of the inward displacement of plastic deformation of the circular shaped lava tube has been estimated through analytical methods. The reanalysis of GSI and derivation of Hoek-Brown parameters for future numerical analysis has been introduced. Additionally, with empirical analysis, the support and remedial action for lava tube deformation has been recommended in this study. This report presents a holistic approach toward considering the complex problem of lunar lava tube stabilisation through the use of in-situ additive technologies and exploits the objective of in-situ resource utilisation (ISRU).
