Cusp displacement catastrophe theory can be introduced to propose a new method about instability failure of the interbed for gas storage cavern in bedded salt in solution mining. We can calculate initial fracture drawing pace of this interbed to obtain 2D and 3D gas storage shapes at this time. Moreover. Stability evaluation of strength reduction finite element method (FEM) based on t... https://www.pomyslnaszycie.com/white-and-green-bulletin-board-border-simply-boho-schoolgirl-style-on-sale/
