Bearing capacity evaluation of small-diameter spiral piles in soft ground subjected to combined loads

Reliability Analysis of Bearing Capacity of Large-Diameter Piles under Osterberg Test

This study gives the reliability analysis of bearing capacity of large-diameter piles under osterberg test. The limit state equation of dimensionless random variables is utilized in the reliability analysis of vertical bearing capacity of large-diameter piles based on Osterberg loading tests. And the reliability index and the resistance partial coefficient under the current specifications are c...

Buckling Behavior of Long Anisotropic Plates Subjected to Combined Loads

Effects of the Tip Location on Single Piles Subjected to Surcharge and Axial Loads

When applying axial load on piles subjected to negative skin friction (NSF), the yielded NSF is gradually eliminated. The process is notably influenced by the tip location (Y) and still a lack of understanding. This paper reports three-dimensional numerical simulations with tip locations Y = 1.00 pile diameter (D), 0.25D, 0.00D, and -1.00D. It is found that, against expectations, the dragload a...

Evaluation of Static and Dynamic Methods for Determining the Bearing Capacity of the Driven Pipe Piles (TECHNICAL NOTE)

Determination of the pile capacity is always a major concern for the safe geotechnical engineering design. Different direct and indirect methods have been proposed for determining pile bearing capacity such as static and dynamic approaches. Each method depends on the condition of the soil and type of pile as well as accessibility to necessary information. In this study bearing capacity of drive...

Lateral Load Tests on Small-Diameter Piles for Slope Remediation

Slope reinforcement and the use of structural pile elements can be an effective slope remediation alternative when conventional remediation practices (e.g., improved drainage) fail to consider the causal factors leading to slope instability (e.g., strength loss due to weathering). An experimental research program was aimed at developing a rapid, cost-effective, and simple remediation system tha...
