Lined　rock　caverns　(LRCs)　are　becoming　the　preferred　option　for　air　storage　at　sites　where　there　are　no　natural　cavities,　such　as　salt　caverns,　and　this　storage　technology　is　being　developed　and　utilized　in　markets　around　the　world.　The　stability　of　the　overlying　rock　mass　is　one　of　the　key　factors　to　ensure　the　successful　operation　of　LRCs.　In　this　paper,　a　stability　assessment　method　is　presented　that　first　calculates　the　potential　fracture　surfaces　of　the　surrounding　rock　based　on　the　limiting　stress　field　and　the　Mohr–Coulomb　damage　criterion,　and　then,　based　on　these　fracture　surfaces,　solves　for　the　factor　of　safety　defined　on　the　basis　of　the　concept　of　strength　reserve.　Using　this　method,　this　study　evaluates　the　stability　of　two　types　of　LRCs,　tunnel-　and　silo-type,　under　three　different　geological　conditions.　The　results　of　the　analysis　show　that　the　silo-type　LRCs　are　more　economical　for　engineering　purposes.　Also,　this　paper　provides　some　guidance　for　engineers　in　site　selection　and　preliminary　design.　©　2024　by　the　authors.
