Abstract
Within the confines of this study, the results of direct shear box tests performed on poorly-(GP) and well-graded (GW) gravel samples are presented. Samples are tested under effective normal stresses ranging from 77 to 205 kPa, and with initial void ratio ranging from 0.42 to 0.53. The estimated peak secant-angles of shearing resistances vary in the range of 49 to 61 degrees. On the basis of the ratio of vertical to horizontal deformation rates, the peak angles of dilation are estimated as 10-16 degrees. These estimated values are concluded to be in coherency with available literature, other than the recommendations of Navfac DM 7.01.
期刊介绍：
The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed.
Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering.
Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
