一种速定地震震中位置的最优化方法
An Optimization Method for Locating Earthquake Centre
-
摘要: 本文先将确定地震震中位置问题转化成求某一指标函数的极值问题,然后用最优化方法 提出了一种确定震中位置的实用方法.方法的优点是适用性好、求解速度快、对台站数量及布 局的依赖性小,在仅有三个台站时,也能确定震中的位置.Abstract: In this paper, the problem of locating earthquake centre is transformed into a problem of searching extreme value of a target function. A practical method is presented using optimization technique. The advantages of this method are as follows: good adaptability, fast response, less depedence on the number and distribution of stations. The method can also be used when there are only three stations.
