摘要利用地下硐库进行压缩空气储能是大规模能源存储的可行方式之一。在研究压气硐库围岩在长期循环荷载作用下的力学及变形特征上，传统模型多采用基于Mohr-Coulumb屈服准则的弹塑性模型或统计损伤模型。然而，这些模型并未考虑到硐库内压低于疲劳阈值的情况。为了解决这个问题，首先论证硐库内压低于疲劳阈值时采用循环硬化模型计算围岩变形模量及位移变形的合理性，然后以轴向残余应变为内变量推导压气硐库围岩的循环硬化模型。在此基础上，研究不同岩性岩石的疲劳参数对压气硐库围岩力学及变形特性的影响。并将现场实验的实测值与模型预测值进行比较。结果表明循环硬化模型可以很好地预测压气硐库的围岩变形。

Abstract：Compressed air energy storage in underground caverns is a feasible solution for large-scale energy storage. In studying the mechanical and deformation characteristics of surrounding rock under long-term cyclic loading in compressed air caverns，traditional models mostly adopt elastoplastic models or statistical damage models based on the Mohr-Coulomb yield criterion. However，these models do not consider scenarios where the pressure inside the cavern falls below the fatigue threshold. To address this issue，the rationality of using a cyclic hardening model to calculate the deformation modulus and displacement of the surrounding rock in the case of the cavern pressure being below the fatigue threshold is demonstrated firstly. Then the cyclic hardening model is derived using axial residual strain as the internal variable. On this basis，the influence of fatigue parameters of different rock types on the mechanical and deformation characteristics of the surrounding rock of the compressed air chamber is studied. The model?s predicted values are compared with the measured values from on-site experiments，demonstrating its ability to accurately predict the deformation of the surrounding rock.
