Abstract
It is considered that pullout characteristics are influenced by properties of soil. Particularly in this study, particle size was focused and a series of pullout tests was carried out with three kinds of sand which have different particle size. It was found that the pullout resistance was larger as the particle size of soil was larger. To discuss the effects of particle size in detail, we observed the deformation of soil around geogrid while it was pulled out. The test results showed that the larger area was deformed with the pullout of geogrid in sand of larger particle size. Therefore, pullout resistance was larger for the large particle size.
