Establishing strategic petroleum reserves is an effective way of addressing shortages in the short-term oil supply. The features of underground water-sealed oil storage caverns include long spans, high sidewalls, no linings and no or few support measures. During the construction of an actual project, the underground water level in some areas can sharply drop, which directly threatens the utility of the water system and the safety of the oil storage cavern. Therefore, it is essential to evaluate the hydrogeological conditions of oil storage caverns properly. The relevant construction methods must be modified based on new surrounding rock classification schemes.Many studies about the analysis, design and the construction of underground storage caverns have been conducted [1][2][3][4][5][6][7]. Many scholars have also investigated
