Abstract [en]

A new large-diameter sampler for sensitive soils has been constructed and tested at the Swedish Geotechnical Institute. The construction was initiated by two current projects. The first is a research project requiring large, high quality samples from which a number of "identical" specimens can be cut out and tested under various conditions. The project includes studies of the behaviour of the soil in the "elastic" range of deformations up to failure in undrained conditions, which puts extra high demands on the sample quality. The second project is a large investigation on slope stability along the Göta river including large areas with quick clays, in which it has been found difficult to obtain high quality samples with ordinary samplers. The new sampler provides 1 metre high samples with a diameter of 200 mm, which are divided into 6 parts with heights of about 150 mm before being sealed and transported to the laboratory. The design of the equipment is based on previous experience from Swedish, Norwegian and Canadian samplers. Considerations have also been made regarding robustness, easy operation and compatibility with auxiliary equipment and drill rigs normally used in Sweden. The equipment has now been tried out in a wide variety of Swedish clays and the results from tests on the obtained samples have been compared to the results from Swedish standard piston samples and internationally proposed criteria for classification of sample quality. The samples have been found to be uniform and to fulfil the proposed criteria for high quality samples.
