摘要
利用裂隙演化的非平衡统计理论对岩体断裂的非线性动力学问题进行简单描述。
The dynamic problem is simply described based on the nonequilibrium statistical theory of crack evolvement,trying to use the hybrid analysis of the statistical theory and scan electron microscope (SEM) way,the characters of acoustic emission (AE) signals coming from rock damage in subsiding area are synthetically analyzed and evaluated.These provide an evidence to reversely deduce and accurately infer the position of rock fracture and damage in subsiding area.
