摘要

在本研究范围内，介绍了对低级配（GP）和级配良好（GW）砾石样品进行的直剪箱试验的结果。样品在77至205kPa的有效法向应力和0.42至0.53的初始孔隙比下进行测试。剪切阻力的估计峰值割线角在49度到61度的范围内变化。根据垂直变形率与水平变形率的比值，估计膨胀的峰值角度为10-16度。除Navfac DM 7.01的建议外，这些估计值与现有文献一致。

Large Scale Direct Shear Box Tests on Gravels

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.
