Pore Pressure Response and Dissipation of Piezocone Test in Shallow Silty Soil of Yellow River Delta

Journal of Marine Science and Engineering, 2022
Soil dilatancy and partial drainage have great influence on the consolidation coefficient assessment of silty soils with clay content of less than 30% in the Yellow River Delta using the CPTu. This paper discussed the effect of soil dilatancy and partial

Stochastic mechanics-based Bayesian method for calibrating geotechnical parameters of Shanghai deep soft clay using CPTU data

Yantu gongcheng xuebao, 2023
The construction of urban deep underground engineering requires scientific calculation. The reasonable constitutive model and accurate geotechnical parameters are the most important support for soil mechanics.

Deterministic and Probabilistic Analyses of the Bearing Capacity of Screw Cast in Situ Displacement Piles in Silty Soils as Measured by CPT and SDT

The Baltic Journal of Road and Bridge Engineering, 2023
The bearing capacity of screw cast in situ displacement piles is mostly unexplored. There is also insufficient research on piles in silty soils. Therefore, five cone penetration tests (CPT) and one piezocone penetration test (CPTu) using direct methods ...

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.

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
