面波频散曲线与H/V谱比曲线联合反演在西安地裂缝探测中的应用
Joint inversion of surface wave dispersion and H/V spectral ratio data with application to detection of ground fissure in Xi'an
摘要
Abstract
In urban subsurface investigations,the characterization of adverse geological structures often relies on two primary methods:passive-source surface wave dispersion curve inversion and horizontal-to-vertical(H/V)spectral ratio inversion.The former uses only vertical-component seismic records,failing to fully incor-porate horizontal-component information;the latter is mainly employed to estimate overburden thickness based on the predominant frequency of H/V spectral peaks,with limited application in shear wave velocity structure inversion.To leverage the advantages of both approaches,this study proposes a joint inversion method that in-tegrates dispersion curves and H/V spectral ratios,making comprehensive use of multi-component surface wave information to improve inversion accuracy and stability.A three-layer horizontal layered model repre-senting uniform sedimentary layers and a three-layer vertical fault model simulating a fault zone were estab-lished.Comparative analyses of dispersion curve inversion,H/V spectral ratio inversion,and their joint inver-sion were conducted.Synthetic tests demonstrate that the joint inversion yields more accurate results.Finally,using the F5 ground fissure in Xi'an as a case study,subway seismic data are applied to validate the feasibility and effectiveness of the joint inversion method in detecting and monitoring urban underground structures.The joint inversion of dispersion and H/V spectral curves provides valuable insights for the development and applica-tion of urban underground space exploration technologies.关键词
