Abstract：To analyze and evaluate the hazard of the leakage accident from underground gas storage caverns in salt rock，a prediction method for the gas leakage mass is firstly established on base of the existing models for calculating gas release rate of gas transmission pipelines and pressure drop of vessels. The analytical results were then validated by comparison with the existing test data. Furthermore，the factors influencing on the gas leakage rate of the underground gas storage cavern in salt rock were discussed. The results indicate that the release rate decreases with increase of the length，and increases with increases of the operating pressure as well as the pipeline diameter. Finally，the gas leakage rate and mass varying with time were evaluated by the proposed method.
