Badania zmian współczynnika filtracji na potrzeby oceny odkształceń konsolidacyjnych gruntów słabonośnych

This paper presents the method of permeability coefficient evaluation based on laboratory tests. In Iaboratory investigations the flow-pump technique has been chosen. In this method the constant discharge capacity of water flow in the soil was applied. The results obtained from flow-pump investigation performed on peat samples indicates non-linear relationships between permeability coefficient and vertical stress as well as void ratio. This characteristic should be taken into consideration in analysis of consolidation course in soft soils.
