Development of an inflight centrifuge screw pile installation and loading system [PDF]

open access: yes, 2016
To simulate the prototype installation behaviour of screw piles at realistic confining stress lev-els, a new installation and loading rig, consisting of two independently-controlled servo-motor drive systems was developed to allow screw pile models to be

Influence of Spacing and Cross-Sectional Shaft of Screw Piles Group on Lateral Capacity

open access: yesDiyala Journal of Engineering Sciences, 2021
Although there are several high-capacity screw piles in use currently, there are few studies on their lateral performance. The aim of this study is to investigate the lateral behaviour of several models of screw pile group (1×2), (2×1), and (2×2 ...

Unraveling deformation mechanisms around FCC and BCC nanocontacts through slip trace and pileup topography analyses [PDF]

open access: yes, 2017
Nanocontact loadings offer the potential to investigate crystal plasticity from surface slip trace emissions and distinct pileup patterns where individual atomic terraces arrange into hillocks and symmetric rosettes.

Experimental and theoretical researches on horizontal bearing mechansim of single screw anchor pile

open access: yesYantu gongcheng xuebao, 2020
The design codes for screw anchor piles have shortcomings in calculation of the horizontal drawing capacity, and the understanding of soil pressure distribution on the anchorage surface is not unified in theoretical researches.
