ABSTRACT

The reliability of non-invasive shear wave velocity (Vs) profiling techniques is assessed for four Ontario highway sites in comparison to invasive methods (N₆₀, s_u, laboratory bender element Vs, borehole geology). Our non-invasive Vs profiles are obtained from joint inversion of surface wave dispersion and microtremor horizontal to vertical spectral ratio peak(s). The overall inter-method average relative difference in soil Vs is 15%. Non-invasive and invasive methods provide consistent Vs₃₀ and earthquake site classification. Multi-method site classification demonstrates greater success of non-invasive and invasive methods to determine the Vs profile and soil properties respectively.

摘要

_{与侵入式方法（N 60}、 s _u、实验室弯曲元件 Vs、钻孔地质学）相比，评估了安大略省四个高速公路站点的非侵入式剪切波速度 (Vs) 剖面技术的可靠性。我们的非侵入式 Vs 剖面是从表面波色散和微动水平与垂直光谱比峰值的联合反演中获得的。土壤 Vs 的总体方法间平均相对差异为 15%。非侵入性和侵入性方法提供一致的 Vs ₃₀和地震现场分类。多方法场地分类证明了非侵入性和侵入性方法在分别确定 Vs 剖面和土壤特性方面取得了更大的成功。
