摘　　要：结合极限分析下限法理论和线性规划构建压气储能洞室极限内压值计算模型,探讨不同洞径及埋深的圆形洞室极限内压值变化规律,并以洞室在开挖后及高压气体作用下的静力许可应力场为基础,对洞室稳定性和洞周应变进行分析.Combining the theory of lower bound limit analysis and linear programming to build within the limit of compressed air energy storage cavern pressure value calculation model,the variation of pressure in the limit of circular cavity with different diameter and depth is discussed.Based on the static allowable stress field after excavation and under the action of high pressure gas,the stability and circumfluence strain of the cavern are analyzed.
