Liquefaction potential and piezocone response
Bulletin of the New Zealand Society for Earthquake Engineering, 1995 A simple approximate analysis is presented for interpretation of cone penetration results when the cone resistance is affected by layering of soils with different stiffnesses. It is argued that the cone resistance senses the presence of a nearby layer elastically, and an approximate elastic analysis is developed to quantify the effect. Good comparisons

Infrastructures, 2021 Overconsolidated (OC) soils may develop a low or negative pore pressure during PCPT. Thus, it is challenging to develop an “on-the-fly” estimation of hydraulic conductivity from PCPT results.

Classification of soft clay in Jiangsu Province based on piezocone penetration tests
Yantu gongcheng xuebao, 2021 The classification results of soft soils in Jiangsu Province are derived through the CPTU data. The soil classification methods based on the CPTU data are reiviewed, then the SBT (soil behavior type) method and the Ic (soil index) method are chosen to ...

Characterization of soil permeability in the former Lake Texcoco, Mexico
Open Geosciences, 2019 The geotechnical subsoil conditions of the former Lake Texcoco represent a complex sequence of highly compressible lacustrine clays interbedded with layers and seams of harder and more permeable materials.

Profiling Stress History from Piezocone Soundings
Soils and Foundations, 1988 ABSTRACT A piezocone data base is compiled from 36 well-documented clay sites with known stress histories. Only transducer readings on the cone tip or just behind the tip were considered. The normalized excess pore pressure to effective overburden ratio (∆ u/σvo') indicated better trends with overconsolidation ratio (OCR) than the parameters (u/qc ...

Insights from CPTu and Seismic Cone Penetration Testing in the Kathmandu Valley, Nepal
Frontiers in Built Environment, 2021 Seismic hazard assessment often relies on static piezocone penetration tests (CPTu) to estimate the cyclic resistance ratio (CRR) and for the evaluation of in situ soil behavior.

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 1064-1080, December 2025.ABSTRACT Northeastern New Zealand has a landscape susceptible to landslides, on account of (1) its proximity to an active plate boundary, (2) steep slopes, (3) young, soft, sedimentary rocks and soils, (4) landuse changes, and (5) rainfall from ex‐tropical cyclones. The interplay of these led to widespread rainfall‐induced landsliding in the first half
