岩石单轴压缩试验Kaiser效应实质的研究
NATURE OF KAISER EFFECT OF ROCKS UNDER UNIAXIAL CYCLIC LOADING
摘要
Abstract
Past experimental evidence indicates that rock on certain conditions exhibits the Kaiser effect(KE)when it is loaded,and the KE of rock has ability to remember its maximum previous state parameters including stress,axial strain and transverse strain.At the same time the accuracy of state parameters′ KE is different with loading stages.Recent experiment indicates that rock also has ability to remember its maximum previous physical parameters such as bulk strain,Young′s module and Poisson′s ratio.“Young′s module memory”which is of both accuracy and stability shows the best among the three physical parameters.Furthermore,the experiment result shows“Young′s module memory”not to be affected by time factor.It demonstrates that the nature of Kaiser effect is memory of its previous physical behavior.关键词
