摘要：

A numerical simulation of natural gas underground storage field in bedded rock salt is proposed, and compared to available in situ measurements in two sites, Tersanne and Etrez (France). Evolution of surface subsidence and cavity volume loss is of main concern. Although the problem is three dimensional, an axisymmetric model for a single cavity is used together with a superposition method previously validated. A good determination of surface subsidence is obtained by a hybrid BEM-FEM model. There is a reasonable agreement between in situ data and numerical values. A long term evalaution of subsidence is then proposed for the next hundred years.
