Özet

The mainpurpose of this study was to investigate the relationship between the undrainedshear strength and the Atterberg limits of quartz clay mixtures using thefalling cone test and the casagrande method. As a result, the penetration depthof the fall cone, which determines the liquid limit close to the value obtainedby the casagrande method, was changed by the presence or absence of finegrained soils. It was shown that the same clay type with a much higher quartzcontent led to smaller undrained shear strength values. The undrained shearstrength value with a small amount of quartz was the lowest; it then increasedwith the increase in fine content. The relationship between the undrained shearstrength and the Atterberg limits for all the samples can be divided into threeparts: (1) quartz clay (kaolinite/bentonite) mixtures ratio, (2) type of clay (plasticity;high - low plasticity), and (3) plastic limit value. Finally, an equation forthe fall cone test used to determine the Atterberg limit of quartz claymixtures, was proposed based on the undrained shear strength and initial watercontent.
