摘要
由于地下层状结构与面波频散曲线之间是一种高度非线性关系,所以面波频散曲线的反演方法应该采用非线性的反演方法。笔者将目前在最优化问题中得到广泛应用的拟牛顿法应用到瑞利面波频散曲线的基阶模反演当中,取得了很好的效果,并通过实例验证了方法的可行性。
The relationship between the dispersion curve of Rayleigh wave and the structure of muhilayered media is nonlinear, so the inversion method of the dispersion curve should be nonlinear. In this paper the authors applied the Quasi-Newton method to the inversion of the fundamental mode, with good effects obtained. With a practical example, the method was verified.
