A CPTU‐Based Prediction Method for Undrained Shear Strength With Quantified Uncertainty

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
The engineering properties of seabed soils are crucial to the foundation design of offshore structures. Among them, the undrained shear strength (su) is a key parameter for evaluating the shear failure resistance of saturated cohesive soils. Although empirical equations based on piezocone penetration tests (CPTU) offer a convenient approach for ...

An Ensemble Method for Soil Parameter Prediction Based on Multisource Data Fusion

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Site investigation is crucial in geotechnical engineering. The cone penetration test (CPT) and the multichannel analysis of surface waves (MASWs) are widely used as geotechnical and geophysical methods, respectively. CPT offers high precision but requires a high cost and only provides soil information at limited locations.

The influence of pore pressure gradients in soil classification during piezocone penetration test

Engineering Geology, 2013
Abstract The standard cone penetration test (CPT) measures the resistance at the tip ( q c ) during constant rate of penetration as well as the friction/adhesion along the sleeve ( fs ). The excess porewater pressures generated as a result of the penetration can also be measured by a piezometer/transducer ( u 2 ) located immediately behind the cone
