Landslide Simulation through Seismic Refraction Tomography

SRT, Landslide, Finite Element Method (FEM), Synthetic Modeling, InversionAbstract
The critical importance of characterizing complex landslide environments for effective geohazard assessment is widely recognized. In this study, the utility of Seismic Refraction Tomography (SRT) for detailed subsurface investigation was rigorously demonstrated through synthetic modeling and inversion. A robust methodological framework was established, encompassing the generation of a realistic 2D subsurface velocity model and the simulation of seismic travel time data. Subsequently, accurate inversion techniques, employing the Finite Element Method (FEM) and Delaunay Triangulation (DT), were applied to reconstruct the internal geological structure. The resulting analysis of synthetic travel times and inverted velocity models, including the clear delineation of velocity contrasts and an assessment of ray path coverage, effectively validated SRT’s capability in mapping subsurface features pertinent to slope stability. This approach is considered to confirm the potential of integrated geophysical simulations, thereby enhancing the understanding of landslide dynamics and providing a powerful tool for reliable subsurface characterization, which is crucial for informed geohazard assessment and mitigation strategies.
