  Accurately determining the crustal velocity structure within sedimentary
basins is crucial for enhancing energy resource evaluation and seismic hazard
assessment. Traditional crustal imaging is challenging due to the interference
of teleseismic P-wave reverberations (TPR). To address this issue, we propose
an inversion strategy that combines multi-frequency TPR and surface wave
dispersion (SWD) to constrain the crustal structure. Both theoretical
simulations and real data tests from two stations in the Songliao Basin
validate our approach. This method shows great promise for improving crustal
structure investigations in complex environments, such as sedimentary basins
and oceanic regions.
