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.

Non‐linear dynamic analysis of buildings founded on piles: Simplified modelling strategies for soil‐foundation‐structure interaction

Earthquake Engineering &Structural Dynamics, Volume 51, Issue 4, Page 744-763, 10 April 2022., 2022
Abstract The paper investigates the problem of Soil‐Foundation‐Structure Interaction (SFSI) for buildings supported on piles through the comparative analysis between the fixed base and the compliant base assumptions. The structure, a nine‐storey residential building (with or without infills), is modelled in non‐linear regime while the piled foundation ...

su‐Based Shaft Friction Design Method and Evaluation for Pipe Pile

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
The shaft friction in clay is essential to bearing capacity of pipe piles. Reasonable selection of design methods and parameters is very important for offshore piles. This paper focuses on the current popular vertical load design methods based on undrained strength for pipe piles, especially for offshore piles.

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 ...

Trunk river and tributary interactions recorded in the Pleistocene–Holocene stratigraphy of the Po Plain (northern Italy)

Sedimentology, Volume 68, Issue 6, Page 2918-2943, October 2021., 2021
Abstract Tributary rivers can contribute significantly to alluvial‐plain construction by supplying large volumes of clastic material. Their relation to the main axial river strongly influences sediment deposition and preservation. The Po Plain is fed by the Po River and a dense network of transverse tributaries draining the nearby Alpine and Apennine ...

Learning decision boundaries for cone penetration test classification

Computer-Aided Civil and Infrastructure Engineering, Volume 36, Issue 4, Page 489-503, April 2021., 2021
Abstract In geotechnical field investigations, cone penetration tests (CPT) are increasingly used for ground characterization of fine‐grained soils. Test results are different parameters that are typically visualized in CPT based data interpretation charts.

Deformation patterns of upper Quaternary strata and their relation to active tectonics, Po Basin, Italy

Sedimentology, Volume 68, Issue 1, Page 402-424, January 2021., 2021
Abstract Despite increased application of subsurface datasets below the limits of seismic resolution, reconstructing near‐surface deformation of shallow key stratigraphic markers beneath modern alluvial and coastal plains through sediment core analysis has received little attention.

Statistical Assessment of Simplified CPTU‐Based Hydraulic Conductivity Curves

Geofluids, Volume 2021, Issue 1, 2021., 2021
Classical theoretical approaches to evaluate CPTU‐based hydraulic conductivity gave the expression of a bilinear relation defined by KD - BqQt, for undrained and drained soils. In fact, a dividing line may be selected with a certain degree of subjectivity, and several undrained/drained points occur in opposite sites, which may make us doubt the ...

Deterministic and Probabilistic Analyses of the Bearing Capacity of Screw Cast in Situ Displacement Piles in Silty Soils as Measured by CPT and SDT

The Baltic Journal of Road and Bridge Engineering, 2023
The bearing capacity of screw cast in situ displacement piles is mostly unexplored. There is also insufficient research on piles in silty soils. Therefore, five cone penetration tests (CPT) and one piezocone penetration test (CPTu) using direct methods ...
