Effect of Travel Path in the SCPT Test Method

摘要

Current analyses of seismic cone penetration (SCPT) test data assume that seismic rays travel in a straight path between the source and receivers. While this holds true for single-layered homogeneous soil, soil layers cause rays to reflect and refract, resulting in a deviation from their normally assumed straight-path geometry. This paper presents results of simulated SCPT tests designed to study the effects of soil layers on travel path length. These results show that, in general, variations between true and assumed direct travel paths are small and can be ignored in SCPT calculations.
