ABSTRACT
This chapter describes the full-scale field test carried out at the Kadoorie Agricultural Research Centre of The University of Hong Kong, where groundwater table was artificially raised to the surface to study the development of loads in the soil nails and compare with that obtained using a finite element approach. Soil nailing is a technique routinely used in Hong Kong whereby closely spaced steel bars are installed into a slope so that the stability conditions of slopes comprising either in-situ or compacted soils can be improved. The chapter also describes the load developed along the instrumented soil nails when the groundwater table was raised to the ground surface. Soil nailing is a technique whereby closely spaced steel bars are installed into a slope to improve its stability conditions. The chapter discusses a comparison of factor of safety of the soil nailed system using conventional limit equilibrium and that from strength reduction technique.
