Evaluation Method for the Liquefaction Potential Using the Standard Penetration Test Value Based on the CPTU Soil Behavior Type Index

Advances in Civil Engineering, 2019
Taking the project of the Su-xin highway treated by using the resonant compaction method as the reference, a new method for the evaluation of liquefaction potential is proposed based on the piezocone penetration test (CPTU) and the standard penetration ...

Analysis of piezocone penetration under different drainage conditions with the two-phase Material Point Method [PDF]

Journal of Geotechnical and Geoenvironmental Engineering - ASCE, 2016
The piezocone penetration test (CPTU) is commonly used to identify the soil profile and to estimate material properties. Depending on the soil type, ranging from clay to sand, undrained, partially drained or drained conditions may occur during cone ...

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.

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 ...
