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 ...

Study on the disturbance and recompression settlement of soft soil induced by foundation pit excavation

Rock and Soil Mechanics, 2021
The deep excavation of foundation pit in soft soil layer will cause serious disturbance to the soil at the bottom of the pit. Affected by excavation disturbance, the mechanical properties and stress state of the soil at the bottom of the pit will change.

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.

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

, 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 ...
