THE MULTIGRID METHOD TO ROCK MECHANICS AND ENGINEERING
多重网格法在岩石力学与工程中的应用

A multigrid algorithm is described in this paper,which can be used to obtain the finite element solution of rock mechanics and engineering problems.The design anddata structure of adaptive multigrid finite element software are discussed in detail.Numerical experiments performed with the stress analysis of underground cavern excavation problems have shown that the multigrid method is an effective matrix equation solver for rock mechanics and engineering problems.
