Abstract

 

The salt caverns construction based on the various stability influencing factors was analyzed using analytic hierarchy process. The gray connection corresponding evaluation model of salt caverns gas storage was also established. The model is based on the consideration of correlation coefficient and the weight distribution of each index, and put the correlation degree as final evaluation index of stability evaluation. Finally, combining with engineering practice, the gray connection corresponding evaluation model is applied to the 3 kinds of salt caverns, using analytic hierarchy process. The evaluation results show that the evaluation model can determine the factors (cavity spacing, the shape of the cavity, the cavity height and so on) affecting degree on the stability of the entire body cavity.
