Excerpt

Recently, the Chinese government has planned to build a large underground rock reservoir for compressed air energy storage plant in Inner Mongolia for electric power generation. The inflation and discharge of compressed air will cause a fluctuation of air pressure on the cavern surface, subsequently leading to a variation of loading on the rock joints around the cavern. Usually, the rate of inflation or discharge of compressed air is not constant (determined by the demand, from tens of kilopascal to more than one megapascal per hour). A similar effect on the rock joints is also encountered in large underground petroleum storage caverns, such as Jurong Rock Cavern under construction in Singapore. As such, the effect of loading rate on the shear behavior of rock joints should be considered. However, this is fundamentally different from the creep behavior of rock joint due to the far shorter loading and unloading time. …
