[PDF][PDF] Interpretation of geotechnical parameters from seismic piezocone tests

PW Mayne - Proceedings, 3rd international symposium on cone …, 2014 - researchgate.net
Soil behavior is complex and thus requires quantification by a reasonably good number of
different engineering parameters. Consequently, the seismic piezocone test (SCPTu) is …

Numerical derivation of CPT-based p–y curves for piles in sand

SK Suryasentana, BM Lehane - Géotechnique, 2014 - icevirtuallibrary.com
