Laboratuvardaki içsel sürtünme açısını ve kohezyon değerlerini belirlemek için yapılan en yaygın deneylerden biri direk kesme testidir. Bu çalışma için, tamamen kuru zeminlerin dayanım parametrelerinin, farklı rölatif sıkılıklar ve normal gerilmelerdeki değişimleri incelenmiştir. Deneysel çalışma direk kesme testi, beş farklı normal gerilme ve sabit numune hacmi altında yapılmıştır. Kumun kohezyonunun sıfır olduğu varsayımı ile karşılaştırma yalnızca içsel sürtünme açısına bağlı olarak gerçekleştirilmiştir. Elde edilen kayma mukavemeti açısı değerleri ile rölatif sıkılık ve normal gerilme ilişkisi, zemin tane çapı değişimi parametresi de göz önünde bulundurularak incelenmiştir. Numunelerin test edildiği rölatif sıkılıklarda, içsel sürtünme açısı gibi fiziksel özelliklerin artışını içeren normal gerilmedeki artışla birlikte maksimum ve artık kayma gerilmesinde de bir artış olduğu görülmüştür. Ayrıca elde edilen sonuçlar, zeminin dane çapı dağılımının içsel sürtünme açısını nasıl etkilediğini göstermiştir.
One of the most common experiments performed in the laboratory to determine the inner drain and cohesion values is the direct cutting test. For this study, the changes in the resistance parameters of fully dry soil, different rational tensions and normal tensions have been studied. Experimental work was done under the direct cutting test, five different normal stretching and fixed sample volume. The comparison with the assumption that the kum cohesion is zero was made only depending on the inner stretching point of view. The achieved sliding strength angle values and the relative stretchness and normal stretch relationship, the ground one diameter change parameters are also studied taking into account. In the ratio tensions in which samples were tested, the increase in normal tensions, which includes an increase in physical characteristics, such as the inner stretching angle, has been shown to be the maximum and now the increase in the sliding tensions. The results also showed how the ground's diameter distribution affects the inner drilling angle.
One of the most common experiments to determine the internal friction angle and cohesion values in the laboratory is the direct shear test. For this study, the changes of strength parameters of completely dry soils in different relative densities and normal stresses were investigated. The direct shear test was performed under five different normal stresses and constant sample volumes. The comparison with the assumption that the cohesion of the sand is zero was made only based on the internal friction angle. The obtained shear strength angle values and the relative density and normal stress relationship were examined by considering the soil grain size distribution. The relative density in which the samples were tested showed an increase in the maximum and residual shear stress as well as the increase in normal stress, including the increase in physical properties such as the internal friction angle. In addition, the results showed how the grain size distribution of the soil affects the internal angle of friction.
