Development and Testing of a Device Capable of Placing Model Piles by Driving and Pushing in the Centrifuge

Abstract

Elastic wave propagation and the practical aspects of pile driving are discussed to develop an understanding of which aspects of pile driving must be modeled most precisely in the centrifuge. The scaling laws are developed. Design and construction of a 5 g-ton (110 g) centrifuge are presented. Construction details of the model pile placement device are discussed. The placement device has the capability of driving individual piles and can model the energy input of any single acting pile driver. The placement device can also push individual and group piles through the application of up to 1.5 million scale pounds. Static load tests can be conducted with the device. Keywords: Pile drivers, Elastic deformation, Soil stabilization, Penetration.
