The importance of accurate pore water pressure measurements when conducting CPTu as exemplified using data collected in Christchurch following the Canterbury earthquake sequence
Piezocone penetration testing (CPTu) is a widely used investigation method for geotechnical analysis and liquefaction assessments. In addition to recording tip resistance (qc) and sleeve friction (fs), pore water pressure (u) is measured by a pressure transducer via a porous filter commonly located behind the…
