Abstract: Determination of interface shear strength is crucial in the design of many geotechnical structures. To study the effect of interface roughness, particle geometry (size and shape), and sand gradation on the interface friction ...

Abstract: This paper presents the results of tensile load tests performed with instrumented model piles with different surface roughnesses jacked into sand samples in a half-circular calibration chamber with digital image correlation ...

Abstract: The time-dependent increase in axial resistance (setup) of jacked or driven piles in sand is still not well understood, and its quantification remains a challenge. In this paper, a series of tests is performed on model ...

Abstract: AbstractThis paper proposes a numerical approach to evaluate the base load–settlement response of cast-in-situ piles in sandy soils. The method assumes that the load response of the pile base can be modeled as the response ...
