Abstract In view of the lack of effective theoretical prediction models for surface subsidence caused by the operation of groups of salt caverns for gas storage，this paper studies the surface subsidence caused by cavern shrinkage of gas storage through the influence function method. The numerical simulation method is used to study the influence function method，including the variation law of the volume transfer coefficient of single cavern and the influencing factors of double cavern. A surface subsidence prediction model based on cavern group effect correction is established using the influence function method. Combined with the engineering experiment of Jintan gas storage，the modified surface subsidence prediction model is used to analyze the subsidence above salt caverns，and a surface subsidence early-warning threshold based on the safety of cavern volume shrinkage is proposed. The conclusion shows that the influence function method can effectively calculate the surface subsidence caused by the shrinkage of the salt cavern. During the operation period of the salt cavern gas storage，the volume transfer coefficient is between 0.6–0.8，and it continuously increases with the increase of the volume shrinkage ratio of the gas storage. Applied to engineering examples，the recommended early-warning threshold for surface subsidence during the operation period of the salt cavern gas storage is that the cumulative value does not exceed 200 mm.

Key words： underground engineering salt cavern gas storage land subsidence influence function method volume transfer coefficient warning threshold
