| Abstract: | Based on the creep fracture experiments of Jinan gabbro and accumulative AE events at various temperatures and confining pressures,this paper suggests the use of the creep fracture strain as a criterion of rock creep fracture,establishes an emperical relationship of the creep fracture strain of rock various temperature and confining pressure,and on the basis of the creep parameters of Jinan gabbro,discusses the method for predicting rock creep fracture and earthquakes. |
