Abstract: The stresses of the most dangerous point on the edge of a cavity are calculated by using of element free Galerkin method(EFGM). The stability of rock-salt roadbed with single cavity is analyzed. The critical loads are presented for different depths of cavity, The numerical result shows that EFGM is not only effective, but also flexible for the stress intensity problem with one cavity.

Key words: rock-salt roadbed, cavity, stability, element free Galerkin method(EFGM)
