COUPLING MODEL OF UNDERGROUND GAS-STORAGE CAVERNS AND ITS APPLICATION IN ENGINEERING
地下水封裸洞储存LPG耦合问题的变分原理及应用

According to the principles of underground gas-storage caverns with water curtain, variational principle in LPG coupling system of stress field, seepage field and gas-storage field of underground gas-storage caverns is established and its FEM program is developed. The programs are applied in engineering, and the numerical model is proved to be reasonable and credible.
