Simulated annealing inversion of multimode Rayleigh wave dispersion curves for geological structure

Crustal structure of south-central Mexico estimated from the inversion of surface-wave dispersion curves using genetic and simulated annealing algorithms

RESUMEN A partir de catorce sismos de subducción, agrupados en dos trayectorias (una perpendicular y otra paralela a la línea de costa), se calculó un apilado sobre las curvas de dispersión de velocidad de grupo. Estas curvas promedio fueron invertidas usando, por separado, los métodos de algoritmos genéticos y recristalización simulada. Los resultados muestran fuertes diferencias entre ambos m...

Rayleigh Wave Dispersion Curve Inversion: Occam Versus the L1-Norm

Determination of Rayleigh wave dispersion curves for near surface applications in unconsolidated sediments

Multi-channel Analysis of Surface Waves (MASW) is a suitable technique for vertical shear-wave velocity profile determination whose efficiency and effectiveness depends on data acquisition parameters and processing procedures. In the present paper we compare the performances of three different methods to determine Rayleigh waves dispersion curves. Such curves are successively exploited for the ...

Joint inversion of ReMi dispersion curves and refraction travel times using particle swarm optimization algorithm

Shear-wave velocity ( ) is an important parameter used for site characterization in geotechnical engineering. However, dispersion curve inversion is challenging for most inversion methods due to its high non-linearity and mix-determined trait. In order to overcome these problems, in this study, a joint inversion strategy is proposed based on the particle swarm optimization (PSO) algorithm. The ...
