Sažetak
Soil water retention curves (SWRCs) are known as the main tool for assessment of unsaturated soil property functions and are used to extend the conventional saturated soil mechanics with unsaturated soil mechanics principles. This paper presents experimental procedures used for determination of the SWRC on undisturbed samples from flysch material. Soil samples were taken from the Valići Landslide (out of the City of Rijeka, Croatia) colluvium material (residual soil) that is composed of completely weathered siltstones from the flysch bedrock. Different laboratory devices and techniques were used to assess the suitability of used procedures and to determine a wide range of suction values present in this type of soil material. Within a low range of matric suction (below 200 kPa), the standard pressure plate extractors and HYPROP device were used. Measurements were extended to the middle suction range using two different suction controlled oedometer devices, with different capacities of high air entry porous disks (HAEPDs). Dew-point potentiometer WP4-T was used to measure medium and high suction values. As the conclusion, some advantages and draw-backs of used procedures for the specific type of soil are presented.
