EXTRAPOLING CPTU DATA IN OFFSHORE FIELDS

Brazilian Journal of Petroleum and Gas, 2023
Laying of the conductor casing is part of the early stages of well designs. Piezocone Penetration Test (CPTu) is a test used in situ to determine geotechnical properties and evaluate stratigraphy parameters, i.e. undrained shear strength and specific weight. This test generally obtains parameters up to a depth of approximately 40 meters. However, since

Prediction Method of Vertical Ultimate Compressive Bearing Capacity of Single Pile in Soft Soil considering the Influence of Gravity

Geofluids, Volume 2023, Issue 1, 2023., 2023
Considering that the pile foundation is widely used in soft soil, in order to improve the prediction accuracy of the vertical ultimate compressive bearing capacity of a single pile, this paper puts forward a calculation model of the pile side friction resistance in homogeneous soil based on the previous research and further deduces the calculation ...

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 ...

Development and Emplacement of Ana Slide, Eivissa Channel, Western Mediterranean Sea

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 11, November 2022., 2022
Abstract Submarine landslides can destroy seafloor infrastructures and generate devastating tsunamis. In spite of decades of research into the functioning of submarine landslides there are still numerous open questions, in particular how different phases of sliding influence each other.

Investigation into the effect of uncertainty of CPT-based soil type estimation on the accuracy of CPT-based pile bearing capacity analysis [PDF]

, 2016
Cone Penetration Test (CPT or CPTu) is commonly used for estimating soil types and also for the geotechnical design of pile foundation. However, the level of agreement between the CPT-based soil types and the traditional identification of soil types ...

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.

Microstructural study of the deformation zones during cone penetration in silt at variable penetration rates [PDF]

, 2015
During conventional cone penetration testing in silt, the soil will normally be partially drained. If the penetration rate varies, time for drainage is altered and therefore the measured cone resistance and pore pressure will change.
