The 2008 Wenchuan (M=8.O) earthquake occurred on the Longmen Shan Fault zone,which was thought to be without the possibility of big earthquake.Based upon the regional tectonic characteristics of the Longmen Shan area, a dynamic model is studied by means of viscoelastic finite element method.The characteristics of stress fields and slip rate fields are analyzed in order to explore dynamical mechanism of the earthquake.
