Analysis of the performance of frequency-Bessel transformation surface wave tomography method in geotechnical engineering investigation

Abstract The frequency-bessel transform surface wave tomography method has emerged as a novel method for surface wave imaging during the past few years. This technique facilitates imaging large-scale crust-mantle structures and enables shallow engineering exploration. Compared to conventional methods like SPAC, it markedly enhances the quality of the surface wave dispersion curve, particularly in higher mode, enhancing the reliability of inversion. Its active and passive source data processing integration is particularly noteworthy, significantly broadening surface wave methods’ application scope. Our research reviews the performance of this technique in addressing common geological issues encountered in geotechnical engineering investigation, such as bedrock surface detection, cover layer detection, karst detection, and permafrost layer detection. Moreover, it recommends this innovative technique’s widespread adoption and further advancement.
