摘要
基于地下水封裸洞储存石油液化气的原理,给出了相应于水封裸洞储气机理的应力场、渗流场以及储气场耦合系统的变分原理,并建立了以结点位移和孔隙水压力为未知量的有限元列式。通过编程并应用于工程,证明了其合理性。
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.
