3-D FINITE ELEMENT ANALYSIS OF NONLINEAR ELASTICOPLASTICITY OF REGIONAL SEISM-DYNAMICS IN HEISHANXIA GORGE REGION ONTHE YELLOW RIVER
-
摘要: 地震动力学背景决定相应区域的地震活动时空分布规律、孕震过程和模式.以黄河黑山峡地区地震活动时空特征为例,将该地区的地震动力学模式概化为共扼滑动模式,并应用弹塑性三维有限元法对其进行了分析计算,揭示了该区地震活动的内在规律.Abstract: Background of seism-dynamics controlled regularityies of the space-time distribution,seismogeny and pattern of regional seismicities. By the sample of space-time characteristic of seismicities in heishanxia gorge region on the yellow river, the text generalize the pattern of seism-dynamics to conjugation-sliding pattern in that area., and analysize, calculate the model by using 3d finite element method of nonlinear visco-elasticoplasticity, reveal the essence of active regularity.
