摘要：

To establish a stability evaluation system, the mechanical parameters of salt rocks, cavity parameters of gas caverns, and operation parameters of gas caverns were considered. Combining each evaluation index's weight with its connection degree based on the entropy and set pair analysis, respectively, the stability levels of gas caverns were determined. The results were consistent with those of the grey correlation analysis, proving that the set pair analysis method applied in the stability evaluation of gas storage is scientific and feasible. The evaluation by the set pair analysis method, which reflects the stability situation more objectively, can not only avoid the outcome disparity due to the uncertainty of distinguishing coefficients, but also obtain the stability level of gas storage, which provides more detailed information for project practices. © 2017, Editorial Department of Journal of Northeastern University.
