Development of an instrumented model pile

An instrumented model pile has been realized to study the displacement pile installation effects in sand in physical model tests. The system includes a model pile, instrumented with axial and horizontal contact stress sensors, and a corresponding calibration apparatus. The development of the instrumented model pile, including numerical analysis...

New method for full field measurement of pore water pressures

A cost effective method to measure pore water pressures in mixed granular media is described using 40 miniature MEMS pore pressure transducers. High accuracy in a single point is exchanged for lower accuracy full field measurements adjacent to the strongbox wall. The system is easily de-aired and calibrated due to the fact that the transducers...

Measurement of stress and strain development around a pile in a photoelastic granular material

This paper presents the results of model pile penetration in a photoelastic material. The soil in this test is represented by an assembly of photoelastically sensitive glass particles. This allows for the determination of stresses in the assembly by the photoelastic method. Displacements around the pile are measured using digital image...
