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

Prediction of stress history and strength of cohesive soils based on CPTU and data fusion techniques

Yantu gongcheng xuebao, 2019
The overconsolidation ratio (OCR) and the undrained shear strength (Su) are the basic mechanical parameters of soils, which can influence the deformation analysis and strength calculation of soils.

Interpretation of CPTu in “unusual” soils

, 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 ...

Preliminary Validation of a Novel Method for the Assessment of Effective Stress State in Partially Saturated Soils by Cone Penetration Tests

Geosciences, 2018
A proper assessment of the soil effective stress state is crucial in many cases to identify a potential geological/geotechnical hazard as shallow landslides or failure of levees that may have a significant impact on human activities and development. This

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.

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.

Use of functional cluster analysis of CPTU data for assessment of a subsoil rigidity

Studia Geotechnica et Mechanica, 2018
This paper shows an example of the grouping of piezocone penetration test (CPTU) characteristics using functional data analysis, together with the results of clustering, in the form of a subsoil rigidity model.
