压缩空气储能硐室围岩的力学响应与变形分析
Analysis of the Mechanical Response and Deformation Characteristics of Compressed Air Energy Storage Lining under Extreme Pressure
摘要
Abstract
Based on numerical simulations,this study investigates the bearing mechanism and stress characteristics of surrounding rock in high-pressure gas storage caverns under hard rock conditions,focusing on the mechanical response and deformation behavior of different rock mass classes at varying burial depths.The results indicate that with increasing burial depth,the displacement,plastic strain,and failure zone of the surrounding rock gradually decrease,leading to improved stability and a more uniform mechanical response.However,increasing burial depth alone cannot fully compensate for the negative effects caused by poor rock quality,and low-grade rock masses still exhibit significant risks of localized failure and deformation.it is recommended that gas storage caverns be preferentially located in Class II or higher-grade rock masses to ensure structural integrity and long-term stability.Furthermore,targeted support and reinforcement measures—such as systematic rock bolting,shotcrete,and partial lining—should be adopted according to specific design forms and geological conditions.关键词
