PRELIMINARY STUDY ON THE TRIGGER DIGITAL SIMULATION OF THE EARTHQUAKE STRESS

On the basis of the finite element method,two-dimensional and three-dimensional simulat finite element models in Southwest area were set up,the three-dimensional finite element models of upper crust,under srust and upper mantle were set up emphatically in Chuandian area.Fanally,the stress adjust situation by the stress change due to the earthquake in the whole Southwest was discussed.It shows that the front earthquake has a trigger action to the next earthquake.So it is usefull that the strong earthquake activity finite element model was used for judging strong earthquake dangerous area in the future.
