Evaluating CPT and CPTu based pile bearing capacity estimation methods using Urmiyeh Lake Causeway piling records

Evaluation of reliability index and safety factors for pile load capacity estimation using CPT results

The reliability index is an important reliability parameter that is necessary for the development of reliability-based geotechnical design. Both the factor of safety (FS) and the reliability index (β) represent safety margin of structures against either failure or limit state. In this study, the reliability index is analyzed and evaluated in reference to the factor of safety currently adopted i...

Seismic Bearing Capacity of Strip Footings on Pile-Stabilized Slopes

This paper develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. The resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. This comparison indicates an acceptable agreement. The variants of the study incl...

Estimating in-situ soil permeability from CPT & CPTu

Engineers often want to estimate profiles of soil permeability (hydraulic conductivity) as part of the site characterization process. Several methods have been proposed to estimate the coefficient of permeability (k) using CPT results. These methods are generally based on two approaches: (1) estimated soil type and (2) rate of dissipation during a CPTu dissipation test. This paper presents upda...
