摘要
本文描述了利用广义最小二乘非线性反演求解同时确定震源位置和速度结构的方法。给出了数值模拟的结果。并应用此方法对唐山滦县地区临时数字地震台网的资料进行了处理。获得了该区地壳地一维速度结构,并讨论了解的分辨率。
In this paper, using the generalized nonlinear least-square inversion given by A. Tarantola and B. Valette, the method of simultaneous determination of velocity structure and source location is described. The numerical modeling results are given. The data obtained from the temporal digital seismic stations in Luanxian sub-area of Tangshan region are processed by using this method. The 1-D crustal velocity structure in this area is obtained and the resolution is also given.
