Abstract

The contact transferring relationship between the steel lining and the backfill concrete in the shallow buried cavern with hard rock is one of the important factors in determining the joint bearing state of steel lining-concrete lining-surrounding rock and the stress level of the steel lining. In this paper, based on the first excavated hard rock gas storage cavern in China, a study on the cyclic contact transferring behavior between steel lining and concrete lining is carried out based on the ABAQUS platform. This study also elucidated the periodic mechanical response characteristics of the composite structure under the air pressure and air temperature. The results show that the air pressure leads to a large plastic zone at the top and bottom of the surrounding rock, and the irrecoverable deformation of the surrounding rock leads to an increase in the gap between the steel lining and concrete lining after pressure removal. The gap is concentrated at the top of the steel lining under the influence of gravity. For continue running after inspection, the contact pressure between the steel lining and the concrete lining and the steel lining’s stresses experience redistribution. The top contact pressure decreases while the steel lining’s stresses increases significantly, becoming a high risk area for fracture. The air temperature changes mainly cause temperature cycling fluctuations in concrete lining. For contact pressure, temperature rise leads to contact pressure increases and temperature drop leads to contact pressure decreases, while the temperature effect for the stresses of the steel lining is reducing stress peak and stress amplitude. When analyzing the strength and fatigue life of sealed steel lining, the contact transferring behavior between steel lining and concrete lining need to be reasonably considered.
