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.

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.

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.

CPTU-based probabilistic model and evaluation method for liquefaction of sandy and silty soils

Yantu gongcheng xuebao, 2023
The liquefaction of cohesionless soils is closely related to the pore water pressure. The in situ testing technology, piezocone penetration test (CPTU) which can directly measure the pore water pressure, has unique advantages in liquefaction evaluation ...

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 ...
