ABSTRACT

Instrumentation comprising of pore pressure transducers in the soil, earth pressure cells on the retaining wall, bending moment strain gauges on the wall, load cells on the props and linear variable transformers for displacement measurements were installed. Digital cameras were mounted in front of the Perspex window for particle image Velocimetry (PIV) purposes (White and Take, 2002) and LED arrays were situated to illuminate the clay cross-section without causing glare, or shadows. In this paper, only pore pressure and PIV data was discussed.
