...Dandan Jin; Jie Zhang; Binghui Wang; Wenxin Liu; Lei Zhang In practical engineering, transient impact loads such as pile driving are common. In this study the dissipation mechanisms of excess pore water pressure ( EPWP ) in saturated sand under impact loading were investigated through integrated...

... encounter distinct soil layering and need to perform under a variety of load cases. For this application, the installation and monotonic tensile load response of multiple helix screw piles in uniform and layered sands were investigated by centrifuge modelling. Standard pitch-matched and pile self-weight...

... the DC_f-s. Consolidated drained triaxial tests were conducted to investigate the effect of sand types on the DC_f-s. By linearly fitting the deformation of the sensing cable with that of the triaxial specimen, the other factors that affect the DC_f-s, such as the confining...

...K. Rainer Massarsch, Dr Tech A mechanism to explain pile shaft resistance during vibratory driving is discussed. One hypothesis is that horizontally oscillating stresses temporarily reduce shaft resistance. Vibration measurements were conducted in medium-dense to dense sand during vibratory driving...

... (W_f/D_p) and sand relative density. The adopted fins of the shaft play a vital function in its torsional capacity. This is thought to be because the section modulus of a fin pile shaft is augmented at the top of the shaft owing to the presence of fins, which lead to a soil–pile–fins...

..., it discusses the influence of sand void ratio and particle size on sand seepage erosion. The results indicate that the erosion area is primarily affected by the void ratio and particle size. In comparison to soil particles ranging from 0.1 to 5 mm and from 2 to 5 mm, those with sizes between 0.1 mm and 2 mm...

... characteristics, especially grain size distribution, and relative density on the obtained CPT–SPT and DP–SPT linear correlations using a newly compiled experimental database for GV-ES sands and the previously published datasets. Correlations were determined using statistical inference, specifically by simple...

... the installation procedure must be considered as well as the in-place performance. The scope of this paper is to consider the calculations appropriate for the installation of caissons in sands. Calculation methods are presented for determining the resistance to penetration of open-ended cylindrical caisson...
