从弹簧滑块到地震预测:BK模型今昔谈

FROM SPRING-AND-BLOCK TO EARTHQUAKE PREDICTION:AN INTRODUCTION TO THE BURRIDGE-KNOPOFF MODEL FOR THE PHYSICS OF EARTHQUAKES

Burridge -Knopoff弹簧 -滑块模型作为一个概念性的地震模型 ,自 196 7年提出以来一直为地震学家和物理学家所关注 ,对BK模型的研究成为物理学与地震学之间的一个活跃的交叉领域 .BK模型的一些性质 ,例如确定性浑沌、自组织、孤立波 ,等等 ,能够为理解地震的性质和解决地震预测问题提供有用的线索 .BK模型与目前的一些悬而未决的复杂性物理问题的联系 ,使它不仅对地震研究 ,而且对更普遍的多体系统问题的研究 ,都有重要的影响 .

The Burridge Knopoff(BK) spring block model as a conceptual model for the physics of earthquakes has attracted much attention among physicists and seismologists since 1967,becoming an active research subject in the interdisciplinary approach to the physics of earthquakes. Certain characteristics of the BK model, such as deterministic chaos, self organization, and solitary waves, among others, provide heuristic clues to the understanding of the nature of earthquakes and shed light on the problem of earthquake prediction. Due to its connection with several outstanding problems in the physics of complexity, the BK model has had significant impact not only on seismology but also on the physics of multi body systems.
