从应力链到声发射
From Stress Chains to Acoustic Emission
摘要：
本文采用有限离散单元法（FDEM）的数值方法研究了一个含颗粒层的地震系统模型。当地层被驱动以剪切颗粒层时，出现应力链系统。应力链赋予该层抗剪切性，并且在故障时发射广播到地层中。作为声发射接收的这些广播提供了对地震系统的颗粒层状态的远程监测。
英文摘要：
A numerical scheme using the combined finite-discrete element methods (FDEM) is employed to study a model of an earthquake system comprising a granular layer embedded in a formation. When the formation is driven so as to shear the granular layer, a system of stress chains emerges. The stress chains endow the layer with resistance to shear and on failure launch broadcasts into the formation. These broadcasts, received as acoustic emission, provide a remote monitor of the state of the granular layer, of the earthquake system.
