Özet

Grain­ size distribution that  is one  of the  base  properties of soils and soil classification  systems gives idea  about  engineering  properties of soils. Determination of grain­ size  distribution derived from mechanical method (sieving) is time consuming and difficult. Hence, the image analysis methods for determination of grain­ size distribution have been  also investigated by several researchers. In that research, the grain­size distributions for ten soil samples with different sizes and  shapes are  determined  with image analysis methods. The  effects of particle  shape (i.e., elongated, flat, spherical) and  volume  computation techniques (cube,  cylinder, ellipsoid, and modified  ellipsoid) on grain­ size distribution were also researched. The results of the research indicated that the shape of particles significantly affected  grain­size distribution. Additionally, modified  ellipsoid  method is determined as the best volume computation method.
