摘要
通过对不同温度和围压条件下济南辉长岩的蠕变破坏实验结果和声发射特征分析,本文提出以岩石蠕变破坏应变做为岩石蠕变破坏判据。建立了岩石蠕变破坏应变的经验关系式。依据实验结果得到相应的济南辉长岩蠕变破坏应变参数,进一步探讨了预报岩石蠕变破坏和地震的方法。
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.
