CPTU correlations for Norwegian clays: an update [PDF]

AIMS Geosciences, 2019
Geotechnical design in clay areas in Norway is mainly based on piezocone (CPTU) tests results. Strength and stiffness parameters are usually derived from CPTU parameters and empirical correlations. In order to improve geotechnical design practice (e.g.

CPTU-Based Offshore Wind Monopile Rigid Bearing Mechanism Analysis

Journal of Marine Science and Engineering
With the development of the offshore wind industry in China, the amount of offshore wind turbines has increased rapidly. Large-diameter steel monopile foundations of offshore wind turbines have been widely adopted in China with lots of marine clay ...

Numerical study of viscous effects during CPTu [PDF]

7th International Conference on Geotechnical and Geophysical Site Characterization
Variable penetration rates during CPTu may impact cone readings through partial consolidation during penetration but also through viscous soil skeleton behaviour. The latter phenomenon is characteristic of dynamic penetrometers during fast penetration in fine-grained materials where tip resistance increases when the penetration rate increases.

Selection among CPTU-Based Liquefaction Models

Procedia Engineering, 2011
AbstractIn this paper, a process is taken to select probabilistic models for liquefaction/cyclic softening potential evaluation based on case histories with piezocone penetration test (CPTu) data. Emphasis of the paper is placed on establishing a relationship between the probability of liquefaction/cyclic softening and the safety factor determined with

Utökad utvärdering av CPTu-resultat

, 2022
In Sweden, it is common to use the CPT - Cone Penetration Test when probing in loose soils. This is mainly because the method is suitable for further assessment of soil layer sequences, pore pressure and forming an estimate of the geotechnical properties in-situ.

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

Advances in Civil Engineering
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.

Evaluation of Pile Lateral Bearing Capacity-Based on Cone Penetration Test Results

Advances in Civil Engineering
To analyze the bearing capacity of pile foundations under horizontal loads, a new method based on the piezocone penetration test (CPTU) data for calculating pile p-y curves was proposed.

Interpretation of CPTu in “unusual” soils [PDF]

, 2016
The paper deals with the interpretation of CPTu in unusual soils, such as shallow clayey layers above the water table and loose, intermediate - permeability soils (loose silt mixtures). The paper shows an approach that could be used for the first type of soil to infer the effective vertical stress from CPTu measurements and in particular from the Ic ...

CPTU CORRELATIONS FOR CLAYS [PDF]

, 2019
As part of the R&D project GEODIP-SP8, a multivariate high-quality database of sensitive clays consisting of laboratory strength and consolidation test results, index parameters and CPTU parameters was established. The present report evaluates, with the help of multiple regression analyses, possible correlations among measured CPTU parameters (e.g ...

Permeability estimates from CPTu: a numerical study

, 2018
Realistic numerical simulations of CPTu in soft soils are now becoming possible thanks to methods like the Particle Finite Element Method (PFEM). They may be used to systematically explore the traditional methods of CPTu interpretation, identify their limitations and propose alternatives.
