Opis:: A source of essential information regarding the behaviour of the soil-reinforcement system can be laboratory pullout tests. In this paper, basic aspects of such testing concerning the equipment used (designed and constructed in the Geotechnical Laboratory of Gdańsk University of Technology) and procedures applied are described. The pullout tests carried out for biaxial polypropylene geogrids embedded in coarse sand are presented. Finally basing on the test results the interpretation procedure for the estimation of elasto-plastic interaction between geogrid and soil is proposed. The method proposed enables determining soil-geogrid interface: stiffness modulus responsible for elastic behaviour of the system in the range of permissible loads, as well as maximum pullout resistance corresponding to limit state.

Opis:: This paper reports results from 1g model tests carried out under single gravity on a skirted foundation installed in sand and subjected to a rapid uplifting force. The effects of displacement rates ranging from 5 mm/s to 450 mm/s on the ultimate capacity, suction pressure inside the skirt compartment, and time of extraction were investigated. Test results indicate that the displacement rate significantly affected the magnitude of uplift resistance, as well as the magnitude of suction under the foundation lid, but had little effect on the relationship between stress and the displacement of the foundation. The shapes of the uplift capacity-displacement curve and the suction-displacement curve were similar for all experimental displacement rates.
