Mechanism of piezocone penetration tests under partial drainage conditions

Yantu gongcheng xuebao
In the natural state, the constraints of soils are between completely drained and undrained conditions. Due to the influences of the probe size, penetration velocity, soil properties and other factors, the partial drainage conditions will occur during ...

Understanding selective triggering of landslide movement in response to rainfall, Gisborne, New Zealand

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

Estimating Plasticity Index Directly from Piezocone Penetration Tests in Saturated Natural Soils

Canadian geotechnical journal (Print), 2023
Plasticity Index, Ip, is a relatable parameter for most geotechnical engineers, because Ip can be used to estimate other soil properties, such as internal friction angle, compression index and low strain shear modulus.

Prediction of stratified ground consolidation via a physics‐informed neural network utilizing short‐term excess pore water pressure monitoring data

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 2, Page 147-165, 10 January 2025.
Abstract Predicting stratified ground consolidation effectively remains a challenge in geotechnical engineering, especially when it comes to quickly and dependably determining the coefficient of consolidation (cv${c}_{\mathrm{v}}$) for each soil layer.

Improving the interpretation of undrained shear strength from piezocone penetration tests by integrating soil physical properties using a hybrid meta-heuristic algorithm

Journal of Rock Mechanics and Geotechnical Engineering
Conventional empirical equations for estimating undrained shear strength (su) from piezocone penetration test (CPTu) data, without incorporating soil physical properties, often lack the accuracy and robustness required for geotechnical site ...

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.
