Investigation of piezocone dissipation test interpretation in clay accounting for vertical and horizontal porewater pressure dissipation with a large deformation axisymmetric penetration model

Frontiers in Built Environment
The piezocone (CPTu) dissipation test is used to characterize how the applied load from the penetrating cone is distributed between the soil and pore fluid during both penetrometer advancement and when penetration is paused.

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.
