Evaluation of the Organic Soil Compressibility from In-Situ and Laboratory Tests for Road Application

The Baltic Journal of Road and Bridge Engineering, 2021
Organic soil is characterised by high compressibility and should be improved so that it can be used for construction. The use of every method of soil improvement requires knowledge of the compressibility parameters.

Unified evaluation method for soil liquefaction potential based on modern in-situ piezocone penetration tests

Yantu gongcheng xuebao, 2022
The cone penetration test (CPT) is a commonly used technique to identify the liquefaction of sandy soil in the world but it cannot reflect the influences of pore water pressure (pore pressure) on the liquefaction behavior. The piezocone penetration test (

Evaluation method for sand liquefaction of Hong Kong-Zhuhai-Macao Bridge based on CPTU tests

Yantu gongcheng xuebao, 2017
The earthquake liquefaction is one of the direct causes for unstable ground and damage of upper structure. Therefore, the liquefaction assessment is an important part of anti-seismic investigation in engineering.

CPTU-based probabilistic model and evaluation method for liquefaction of sandy and silty soils

Yantu gongcheng xuebao, 2023
The liquefaction of cohesionless soils is closely related to the pore water pressure. The in situ testing technology, piezocone penetration test (CPTU) which can directly measure the pore water pressure, has unique advantages in liquefaction evaluation ...

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

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.
