Hi.
From my experience, the correlation between DPSH tests and SPT depends largely on the local conditions, so what we usually do is the following:
- establish a preliminary geotechnical investigation programme with a couple of SPT's and DPSH's in the same locations;
- establish correlations between DPSH and SPT with sufficient reliability;
- use the DPSH to refine the mesh of the site investigation.
Hope it helped.
Best regards.
