Determining Shear Wave Velocity by Seismic CPTU

, 2016
Tässä työssä tutkittiin seismisen CPTU-mittauksen käyttöä saven leikkausaallon nopeuden mittauksessa. Mittaus tehdään tavanomaisen CPTU-kairauksen yhteydessä lähettämällä maan pinnalta leikkausaalto maaperään ja se vastaanotetaan CPTU-kairan kärjen ...

A numerical study of deep excavations adjacent to existing tunnels: Integrating CPTU and SDMT to calibrate soil constitutive model

Accurate determination of parameters for an advanced soil constitutive model highly relies on laboratory testing, even though it is notoriously difficult to obtain undisturbed samples for soft soils. This study explores the potential use of in-situ tests,

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

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.

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 ...
