| 摘 要： | 本文运用岩石的损伤理论,通过对岩石材料微元强度的统计分布假设,得到声发射积累N随应变ε的变化规律,并对于循环加载情形,给出了Kaiser效应函数的通式。文中还证明,声发射积累N的变化与损伤参量D具有一致性,得到了用声发射积累N描述的岩石本构关系。理论结果与实验资料吻合很好。

| Abstract: | The damage theory of rock is used to introduce the statistic distribution function of microelement strength for rock materials, in which the regularity of acoustic emission counts N vs. strain e is deduced theoretically. For the cfect loading condition, the Kaiser effect function is also given in this paper. It is proved that the acoustic emission count N shows no difference with damage parameter D. The acoustic emission count N is therefore used to describe the constitutive relation of the rock. The theoretical result agress quite well with that from experiments. |
