An analysis of multi-channel surface wave’s Thomson-Haskell forward modelling

Abstract

Multi-channel Analysis of Surface Wave is a geophysical method based on the dispersion curve obtained from Rayleigh wave to predict the stiffness of subsurface structure. To do this, one have to solve the forward modeling first. Thomson-Haskell method which was introduced by Thomson and Haskell is among the first methods used for this purpose. Unfortunately, Thomson-Haskell method has a problem on the  stability when it is implemented numerically. In this papers, authors want to code Thomson-Haskell method to examine the stability property of Thomson-Haskell method which hasn’t been discussed clearly in other Thomson-Haskell’s relating papers. This will put the conerete stone for the next step of solving the inversion problem of examining near surface soil.
