Experimental Investigation and Visualization of Failure Surfaces in Pipe-Soil Interaction Problems Using PIV Technique

In this study, the effect of relative density on bearing capacity was investigated for cases in which a pipe is buried within the zone of influence. As a novelty, failure mechanisms are experimentally determined using Particle Image Velocimetry (PIV). Within the scope of the study, six different physical model experiments were carried out for this purpose. In these experiments, the load imposed on the neighboring surficial foundation model and the resulting displacements relationship were also determined. The results suggest density dependency of the distribution of deformations.
