简述了最近20年来国内外岩石高速摩擦实验研究领域的进展和动态:岩石高速摩擦实验技术的发展实现了对高滑动速率、大位移的地震过程的实验模拟;其结果揭示了岩石和断层泥在地震滑动速率下的力学性状,深化了对断层滑动弱化机制、临界滑动距离、以及地震发生过程的认识和理解;实验在假玄武玻璃成因方面取得了重要进展,并提出了断层发生地震滑动可能留下的其它地质证据,可望为研究断层滑动性状与地震物理过程提供新的思路和信息。岩石高速摩擦实验今后的发展方向主要包括:发展具有加温系统和孔隙压系统的岩石高速摩擦实验装置,研究水热作用下岩石和断层泥的高速摩擦性状;室内实验和地震资料分析相结合研究断层滑动和地震机制;室内实验和野外地质调查相结合探索断层发生地震错动的地质证据等等。
The progress and dynamics of high speed friction experiments in rock and soil at home and abroad in recent 20 years are briefly introduced. The development of high speed friction test technology for rocks has realized the experimental simulation of the seismic process with high sliding velocity and large displacement. The results show that the rock and fault mud The mechanical properties under the earthquake slip rate deepen the understanding and understanding of the fault slip mechanism, the critical slip distance and the process of earthquake occurrence. The experiment has made important progress in the genesis of false basaltic glass and proposed the possibility of earthquake slip The remaining geological evidence is expected to provide new ideas and information for the study of fault slip properties and seismic physical processes. The future development of rock high-speed friction test mainly includes: developing a rock high-speed friction experimental device with heating system and pore pressure system to study the high-speed friction properties of rock and fault mud under hydrothermal conditions; combining laboratory experiment with seismic data analysis Fault slip and earthquake mechanism; combined with laboratory experiments and field geological surveys to explore the geological evidence of fault dislocation in faults and so on.
