声发射信号与尖点突变模型预测岩爆
Prediction of rockburst based on acoustic emission signal and cusp Catastrophe model
摘要
Abstract
In order to study the relationship between the stress and the AE number and energy of the rock,this paper studied the stress and the intensity of the rock under the condition of uniaxial loading and unloading.The experimental results show that in the laboratory experiments of rock burst,the rock only passes through the initial compaction stage,elastic deformation stage and non elastic deformation stage.In the initial deformation stage,the AE number of the rock has a small amount of short time.During the elastic deformation stage,the AE number and energy content of the rock can grow rapidly.关键词
