The main objective of this research is to develop a state-of-the-art optical system that can non-intrusively measure three-dimensional (3-D) internal soil deformation using transparent soil. Transparent soil is made of amorphous silica with a pore fluid having the same refractive index. It exhibits strength and deformation behaviour similar to natural soil and has been used by many researchers in various geotechnical studies. The objectives of this research are threefold: 1) to develop a 3-D deformation measurement system; 2) to better understand the development of soil deformation during cone penetration; and 3) to advance soil-structure interaction modelling using transparent soil. The ultimate goal is to apply the developed system to understand fundamental behaviour of the soil mass.
