地震断层面上凹凸体和障碍体含义的解析
Analysis on the meaning of the asperity and barrier located on the seismic fault plane
【摘要】 由凹凸体和障碍体研究引入的非均匀地震破裂模式,可解释主震前破裂的成因及主破裂之后的应力集中,对地震危险性分析具有重要的理论价值。本文在国内外研究成果的基础上,深入研究了凹凸体和障碍体在地震破裂过程中的作用和意义,解析了凹凸体和障碍体的本质含义,对比分析了两种模式的异同之处,给出了两种模式在不同滑动模型中的适用性,为地震安全性评价提供了有力的理论依据。
【Abstract】 The model of asperity and barrier could explain the complex components and the mainshock rupture of seismic waves as well as the main rupture stress concentration.It has great theoretical value for seismic hazard analysis.Based on the results of previous studies in domestic and abroad,we studied the effect of asperities and barriers in the process of seismic rupture,and analyzed the meaning of asperity and barrier.We also compared the similarities and differences between asperity and barrier.The applicability of the two models in different sliding model was presented.The study provides a strong theoretical basis for seismic safety evaluation.
【Key words】 asperity; barrier; inhomogeneous body; seismic fault plane;
