🎯 CPT Databases

Cone Penetration Test Data Collection for Spatial Variability Studies

→Back to All Databases

Leader: Armin Stuedlein

These databases are mostly CPT clusters, i.e., multiple CPTs are conducted in a local site.

The names of the databases are in the format of A/B/C:
A: Type of in-situ test (CPT or CPTU)
B: Number of soundings
C: Rough size of sounding area

Please contact Armin Stuedlein if you want to contribute databases.
