Abstract

Abstract

In this paper, strain softening model is used for modeling the Wenchuan earthquake.Results shows that this earthquake was caused by compressing of Qinghai-Tibet Plateau and block of Sichuan Basin.The stress drop, energy release amount, the magnitude of dislocation of fault, coseismic displacement, displacement before earthquake and earthquake recurrence intervals are given by the modeling.The modeling results are in good agreement with geologic and geomorphologic survey and others data.
- Wenchuan earthquake,
- Longmenshan fault,
- strain-softening model,
- unsteady model of earthquake
