摘要
利用岩石破裂过程数值模拟软件RFPA对点荷载下岩石的声发射特征进行数值模拟,通过对试验循环声发射事件数强度百分比、声发射累积数的应变百分比及声发射空间分布进行对比,发现点荷载下岩石不仅对先期应力具有很好的记忆效应,对先期最大线应变也有明显的记忆能力.
Numerical simulation on acoustic emission of rock under point loading by using a rock failure process analysis code（RFPA）is carried out, The results of numerical simulation are analyzed on the intensity percentage of AE events, strain percentage of AE accumulative events and spatial distributions of AE. The results show that under point loading rocks have memorizing power to previous maximum principal stress and previous maximum linear strain.
