An Analytical Study on Penetration and Pore Pressure Dissipation of Piezocone Test in Typical Normally and Over-Consolidated Silty Clays

Applied Sciences, 2023
The degree of the over-consolidation ratio (OCR) of silty clay affects the soil’s mechanical properties and in situ test results. The present study utilized numerical analysis to investigate the behavior of cone penetration and pore pressure dissipation ...

Prediction Method for Overconsolidation Ratio of Marine SoftSoil Based on the Piezocone Penetration Tests

Advances in Civil Engineering, 2019
Because of the strong structural and sensitive behavior, the properties of marine soft soil change greatly when subjected to external disturbances, which leads to great difficulty in reflecting its real mechanical properties in the laboratory soil tests.

Tailings Behavior Assessment Using Piezocone Penetration Test

Minerals
Intensive economic development is associated with an increasing demand for raw materials, including minerals. An illustrative example of this issue is the development of the copper industry. A significant problem arising from the scale of copper production is the management of an ever-growing amount of post-flotation tailings.

Dominant factors in MiniCone, CPT and pile correlations: A data‐based approach

Deep Underground Science and Engineering, Volume 2, Issue 4, Page 346-358, December 2023., 2023
Using a database comprising MiniCone and cone penetration test (CPT) records in the field and physical modeling with a variety of cone diameters, case study records have been obtained from 140 tests compiled from data from 26 sources. The sources include the results of 20 physical modelings and field data from six sites in 10 countries.

The effect of heterogeneities and small cavities on levee failures: The case study of the Panaro levee breach (Italy) on 6 December 2020

Journal of Flood Risk Management, Volume 16, Issue 2, June 2023., 2023
Abstract This article discusses the levee failure that occurred on 6 December 2020 at Castelfranco Emilia, near Modena (Italy), showing that it cannot be explained without assuming the presence of local heterogeneities or a small cavity. The possible presence of these defects is supported by evidence derived from historical data and site observations ...

Sedimentary facies characterization through CPTU profiles: An effective tool for subsurface investigation of modern alluvial and coastal plains

Sedimentology, Volume 70, Issue 4, Page 1302-1327, June 2023., 2023
ABSTRACT Cone penetration tests, a method that is typically used to determine the engineering properties of soils, can be used as an effective tool for refined subsurface stratigraphic investigations of alluvial and coastal plains, aside from the geographic location.
