CPT

Over the years, methods to assess cyclic liquefaction potential based on piezocone penetration tests (CPTu) have been developed. This paper presents a comparative study between three CPTu-based methodologies, mainly in terms of the normalization procedures of overburden stresses, equivalent clean sand resistance, and magnitude scaling factor (MSF). Four...

This paper highlights the importance of linking regional geology to geotechnical ground investigation when estimating the pre-consolidation pressure σ’p of Quaternary clay deposits from piezocone tests. The work comprises a comprehensive site characterization from boring logs, piezocone tests and laboratory oedometer tests carried out at the Tubar&atild...

The management and remediation of contaminated sites are strongly dependent on the diagnosis process during the site characterization program. A Conceptual Site Model (CSM) elaborated by use of high-resolution site characterization (HRSC) tools allows for a detailed diagnosis of geo-environmental issues. The piezocone (CPTu) test is a high-resolution to...

Cone penetration in mixed or intermediate soils (soils containing mixtures of sand, silt and clay) is neither fully drained nor fully undrained at the standard cone penetration rate of 20 mm/s. Considerable research, mainly relying on centrifuge tests, has been undertaken to quantify the effects of penetration rate (and thus partial drainage) on cone re...
