岩体中应力波传播衰减规律研究进展OA北大核心CSTPCD

In order to reveal the attenuation mechanism of stress waves produced by geological structure changes or blasting under different influencing factors,with the help of displacement discontinuity method and equivalent continuum method,scholars have studied the influence of stress wave propagation attenuation law on the incident,propagation and transmission stages of the complete propagation process.The study results show that,waveforms,rock mass properties and joint properties all have significant effects on its attenuation characteristics.This review summarizes the above research methods,discuss the similarities and differences between them,and put forward some urgent problems on the basis of this.This study provides a reference for fully understanding the attenuation law in the process of stress wave propagation,improving the wave theory and improving the safety of practical engineering.
