- Description
- This paper summarises findings of laboratory, in situ and full-scale tests performed at the National Soft Soil Field Testing Facility, established by the ARC Centre of Excellence for Geotechnical Science and Engineering near Ballina, New South Wales. A 9m-thick soft estuarine clay deposit dominates the subsoil profile there, which is typical of foundation conditions along the eastern and southern coasts of Australia. The variation of index and mechanical properties with depth is presented along with measurements of settlement, pore pressure dissipation and lateral deformation below a 3m-thick trial embankment on PVD-improved soil, over a period of 3 years. The presentation concludes with a short discussion on the key mechanisms governing the observed response, essential for the prediction of the behaviour of embankments on similar soft soils.
