地震前兆的数值模拟
Numerical simulation of seismic precursor
摘要
Abstract
Aimed at seeking an alternative to homogeneous geological model which suffers disadvantages,such as,inhomogeneity of practical crustal media and manual specification of terminal region of rock failure,in simulating seismic precursor,this paper introduces inhomogeneous geological model to simulate seismic precursor by means of ANSYS 12.0 numerical simulation software.The simulations show that weak medium areas are main areas where seismic precursor may occur,and complexity of seismic precursor may mainly lie in complicated distributions of weak medium areas.The simulations prove a better explanation for seismic gap,earthquake prediction models of bilateral jumping and denseness-quietude-large earthquake and are very beneficial to study of seismic forecasting.关键词
