Set-up effects of piles in sand tested in the centrifuge [PDF]

, 2014
The bearing capacity of piles increases over time. Research has shown that this is caused by an increase in shaft friction combined with a constant or only slightly increasing base capacity.

Reducing driving forces for pressed-in piles [PDF]

, 2012
Pile jacking techniques use static loading to install sheet piles with minimal environmental effects, such as noise and ground vibrations, which are often associated with other methods of driven piling.

The Correlation between Penetration Pressure Required to Install Pile Foundation and to Insert Bi-cones in Cone Penetration Test

Civil Engineering Dimension, 2019
One of the common methods used to install pile foundation is hydraulic jacked-in machine. In this method, a pile is pushed down into the ground up to the predetermined depth. The method has similar principle to that of Cone Penetration Test (CPT).

CHD pile performance, Part I:Physical modelling [PDF]

, 2016
The Continuous Helical Displacement (CHD) pile is an auger displacement pile developed by Roger Bullivant Ltd in the UK. It has performance characteristics of both displacement and non-displacement piles due to the nature in which it is installed.

Bearing Capacity of Closed and Open Ended Pipe Piles in Clayey Soil [PDF]

Engineering and Technology Journal, 2016
This paper investigates the impact of close and open ended condition on the capacity of pipe piles installed in medium clayey soil using pressed or jacked and hammered techniques and tested under the effect of vertical static compression load.

Investigation of Pile Behaviour using Rotary-Jacking Method

IOP Conference Series: Materials Science and Engineering, 2021
Abstract This research investigates the installation of a new pile using the rotary and jacking method. The use of hydraulic ram to apply static jacking force does not produce the noise and ground vibration produced by the traditional percussion and vibro-hammer methods.

Structural Behaviour of Axially Loaded Concrete-Filled Steel Tube Columns during the Top-Down Construction Method

Applied Sciences, 2022
The paper discusses the structural behaviour of concrete-filled steel tube columns (CFT) when applied to the top-down construction method as temporary internal supports for ceilings.

Pile penetration in crushable soils:Insights from micromechanical modelling [PDF]

, 2019
A 3D discrete element model (DEM) was used to simulate calibration chamber experiments of a cone shaped tip pile penetrating into crushable granular media. Both monotonic and cyclic jacking are considered.
