A numerical analysis of CPT-based tip resistance prediction during pile installation in clays [PDF]

7th International Conference on Geotechnical and Geophysical Site Characterization
Accurately predicting the installation resistance of offshore piles is important for their design and application. The cone penetration test (CPT) is the most widely used in situ sounding tests for pile drivability analysis and capacity prediction. While

Mobilized side and tip resistances of piles in clay

Computers and Geotechnics, 2010
Abstract This paper presents a procedure to assess the mobilized pile side and tip resistance versus pile head and tip settlement under axial load in clay soil. The load transfer (t–z) curve is evaluated at any point on the loaded pile based on the combined pile tip/side resistance–displacement mechanisms along the length of the pile.

Dynamic pile impedances for fixed-tip piles [PDF]

Soil Dynamics and Earthquake Engineering, 2017
The behavior of a laterally loaded pile with fixed-tip boundary condition (i.e., displacement and rotation, are perfectly restrained) is evaluated using a recently proposed, improved Tajimi-type model.

Effect of Spatial Correlation of Cone Tip Resistance on the Bearing Capacity of Piles

Journal of Geotechnical and Geoenvironmental Engineering, 2013
AbstractThe cone tip resistance (qc) from cone penetration tests (CPTs) is widely used to determine the bearing capacity of piles. Although it is widely known that soil properties are spatially correlated, the spatial correlation of qc is not considered in the current methods for predicting the bearing capacity of piles.

Study of the Vertical Bearing Capacity of a Single Pile in Saline Soil Considering Variations in the Shear Stiffness Coefficient

Journal of Testing and Evaluation
A series of laboratory tests were carried out to investigate the vertical bearing capacity of a single pile in saline soil. In addition, an elastic-plastic solution is proposed for an axially loaded single pile considering the variation in the shear ...
