Investigation of Two-Dimensional Interaction between Piles due to Pile Driving Action

Surface Shape of Two-Dimensional Granular Piles

We study the surface shape of two-dimensional piles using experiments and a continuum theory for surface flows of granular materials (the BCRE equations). We first obtain an analytical solution to the BCRE equations with a simple transformation and show that the surface shapes thereby predicted are in good agreement with the experimental results. By means of such an analytical solution, we find...

Binary Mixtures of Two-Dimensional Granular Piles

Previous work on the maximum angle of stability of granular material piles had shown a dip pattern, with lower angles of stability for mixtures of hexagons and dimers or singles made out of ball bearings. This purpose of this study was to confirm this pattern for mixtures of different shapes, namely doubles and large diamonds and small and large triangles. This was done by recording footage of ...

Investigation of Peak Particle Velocity Variations during Impact Pile Driving Process

Impact pile driving is a multi-component problem which is associated to multi-directional ground vibrations. At first, vibration is transferred from the hammer to the pile and then to the common interface of pile and soil. This is then transferred to the environment and has great impact on the adjacent structures, causing disturbance to residents and also damage to the buildings. It is of high ...

Modeling of vibratory pile driving

Vibratory installation of piles and casings can be extremely economical and therefore the contractors’ preferred method of pile driving. Compared to impact pile driving it also has the advantage of reduced noise pollution. Unfortunately, this installation method is still fraught with uncertainties. The foremost question is driveability and equally important is the question of bearing capacity o...
