地壳岩石层由板块、断层和其间的断层泥构成,在研究地震前兆信息传播这类准静力学问题时,应将其作为大尺度离散态颗粒物质体系处理.地震孕育过程中,在大地构造力驱动下,岩石层块克服所受摩擦力和边界断层泥阻力发生滞滑移动.当岩块间断层泥受挤压后其强度增大到一定程度时,又推动下一岩石层块滞滑移动,就这样渐次使其他岩石层块发生移动,并以力链形式分布和传递.文章给出了此模型的物理依据和实际观测例证;通过模拟实验和分析阐述了力-移动-形变在地层中分布的表达形式和传播时间序;说明了地震前兆信息的主要特征及其与地震发生之间的关联,以及探测有效地震前兆信息的方法原理.同时,论述了用颗粒物理原理与连续介质观念对地震前兆认识的本质区别,解释了连续介质观点难以理解的若干地震学问题.
The crustal rock layer is composed of plate, fault and fault mud between them. When studying quasi-static problems such as earthquake precursors information dissemination, the crustal rock layer should be treated as a large-scale discrete state particulate matter system.In the process of earthquake geology, Under the driving force, the rock block overcomes the frictional force and the mudstone resistance of the boundary fault, and when the strength of the mud is increased to a certain degree, , So that other rock mass gradually moves and distributes and transmits in the form of force chain.The article provides the physical basis and practical observation examples of this model.It also expounds that force-displacement-deformation in the formation through simulation experiments and analysis Distribution of the forms of expression and propagation time series; described the main features of earthquake precursors information and its association with the occurrence of earthquakes, as well as the principle of detection of effective earthquake precursors information principle.At the same time, discusses the use of particle physics and continuum concept The essential difference in understanding of earthquake precursors explains a number of seismological issues that are difficult to understand in terms of continuum media.
