Surface wave method has a great potential for rapid determination of shear wave velocity (Vs) profile of the ground. However, it has an inherent limitation in the interpretation of test results due to the assumption that the ground is layered horizontally. Numerical simulation using finite element method has been used to assess the effects of the sloping surface on wave propagation and dispersion characteristics. Finite element model was optimized for surface wave method to satisfy both accuracy and efficiency in the computation, and the applicability of finite element model for the surface wave test was verified by comparison of the dispersion curve with the theoretical solution. The effects of slope angle, stiffness contrast, and the testing direction on the dispersion curve were studied. The propagating shape of wave fronts in the sloping surface was also visualized. From the results of the numerical simulation, it was concluded that the Vs profile of material beneath the slope could be derived reasonably using a source and receiver aligned normally to the sloping surface. Field applications were performed to estimate the reliability of surface wave method on sloping ground. Through field applications and comparison with other test results, the accuracy and applicability of surface wave test on the sloping surface were verified.
