ABSTRACT
This paper describes a novel system developed for the extraction of large, intact soil samples for translational soil shear strength tests on soils of steep agricultural slopes in the Andes of Bolivia ("Nail Cage Soil Sampler"). When tested these produced results with very low scatter. By keeping the samples intact the technique enables shear tests to be conducted elsewhere on level ground. The device isolates a plinth of soil and facilitates intact removal of the soil through the use of a "cage" of steel stakes or nails . It is concluded that the device helped to ensure the validity of the results. Keywords: soil extractor, in-situ shear-box, vegetation and slope stability, Andean valleys, Bolivia
