摘要
在地震断层参数的反演中,选取合适的反演方法,对于反演的结果具有至关重要的意义,模拟退火法是一种非线性的反演方法,为了验证此方法在地震断层反演中的准确性,以2004年的仲巴6.7级地震为研究对象,采用模拟退火的方法,通过调用Rongjiang Wang的Okada程序,对用四叉数方法处理过的INSAR地震数据进行反演,从而得到该次地震的断层参数。
It is very important for the inverting result to select appropriate inverting method in the inversion of earthquake fault parameters.Simulation annealing method is a non-linear inversion method.In order to validate the veracity of the method in earthquake fault inversion,the 2004 Zhongba earthquake of M6.7 is studied by using the simulation annealing.Using Okada program written by Rongjiang Wang,the INSAR earthquake data processed beforehand by the method of quarter-number is inverted and the fault parameters of the earthquake are figured out.
