Numerical study on mechanical characteristics of the Pingjiang pilot cavern for compressed air energy storage
摘要
Abstract
In order to understand the stress characteristics of underground gas storage,the experimental study of the underground granite test reservoir of Pingjiang Pneumatic Energy Storage in Hunan Province is carried out.Based on the FLAC3D platform,the thermodynamic coupling numerical analysis method is used to study the stress characteristics of Pingjiang pressure gas storage test library under temperature and pressure cycle.The results show that:1) The temperature,displacement and stress of the sealing layer,concrete lining and surrounding rock show significant periodic characteristics under the action of internal air pressure and temperature cycle.2) The cyclic load is measured in the vicinity of the wall.The temperature,displacement and stress of the point are much greater than the temperature,displacement and stress at the point of the wall,and there is a lag between the temperature of the surrounding rock at the wall and the air temperature in the test reservoir.Considering the temperature stress condition,the displacement of the measuring point and the first principal stress ratio are larger than the temperature stress,and the more the number of cycles,the greater the numerical difference.关键词
