Spatial variability in surficial Christchurch soils via 5 m shear wave velocity Vs5
Type of content
This paper provides a summary of the development of a shear wave velocity (Vs) model for the greater urban area of Christchurch, New Zealand. The model is based on the application of the recently developed Christchurch-specific empirical correlation between Vs and cone penetration test (CPT) data (McGann et al. 2015a,b) to the large existing high-spatial-density database of CPT logs in the Christchurch region (CGD 2014). Applications of this Vs model are demonstrated through the development of a map of time-averaged Vs in the first 5 m below the surface and typical Vs profiles for different regions within Christchurch.
