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 ...

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 ...

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.

Deep Hydraulically‐Active Fractures in Sensitive Clay Deposits: Implications for Groundwater Flow and Slope Stability

Geophysical Research Letters, Volume 50, Issue 9, 16 May 2023., 2023
Abstract Landslides in sensitive post‐glacial marine clays are one of the major geological hazards in Canada, Norway and Sweden. Current hydrogeological conceptual models used for slope stability analyses in these deposits consider simple groundwater flow conditions within a homogenous, isotropic, massive clay deposits, where fractures are surficial ...

Probabilistic approach for seismic microzonation integrating 3D geological and geotechnical uncertainty

Earthquake Spectra, Volume 39, Issue 1, Page 310-334, February 2023., 2023
A novel probabilistic methodology for regional seismic site characterization is proposed and applied to a region with highly heterogeneous surficial geology and varying soil sediment thickness and stiffness. The method combines various sources of geological and geotechnical uncertainties to develop a three‐dimensional (3D) shear‐wave velocity (Vs ...

Compositional, micromorphological and geotechnical characterization of Holocene Tiber floodplain deposits (Rome, Italy) and sequence stratigraphic implications

Sedimentology, Volume 69, Issue 4, Page 1705-1737, June 2022., 2022
Abstract This study reports a high‐resolution micromorphological characterization of floodplain deposits to investigate the relationships among compositional, textural and geotechnical data, and integrate soil micromorphology with sequence stratigraphy.
