Inversion of Dispersion Curve of Rayleigh Wave Based on Enhanced Whale Optimization Algorithm
The enhanced whale optimization algorithm is a new swarm intelligence optimization algorithm.Compared with the traditional algorithm,its performance is more excellent.The Rayleigh wave dispersion curve inversion of shear wave velocity can accurately characterize shallow strata,which is a reliable means for the engineering prospecting field.The use of Rayleigh wave can effectively identify the occurrence of high-velocity or low-velocity layers in the local strata,but the inversion of Rayleigh wave dispersion curve is a multi-extremal and nonlinear problem.Compared with the traditional linear inversion,the enhanced whale optimization algorithm if used can be more quickly close to the extreme value or escape the local minimum,and its rate of convergence is more quickly,which meets the demands of engineering prospecting.
