This paper presents the result of an extensive series of experimental investigation carried out in triaxial and cyclic direct shear tests on sands having various properties, which were obtained from different locations in Turkey and in Northern Cyprus. In order to investigate the link between strength and physical properties (i.e., shape) of the sand particles, three series of triaxial tests (Consolidated-Drained, CD; Consolidated-Undrained, CU; and Unconsolidated-Undrained, UU) for each were performed under three different confining pressure values (450 kPa, 500 kPa, and 550 kPa) with a back pressure of 400 kPa. The cyclic shear behaviour of the sands was tested by considering the normal stresses of 50 kPa, 100 kPa, and 150 kPa. Experimental results in both triaxial and cyclic direct shear tests showed a relation between the physical properties of the sands and the behaviour of them under monotonic and cyclic loading. The given pictures show the physical differences/similarities among the sands used during the investigation. The goal of the presented experimental investigation is to have an understanding of the behaviour due to shape characteristics (i.e., roundness, sphericity) of these four types of sands (Narli, Birecik, Trakya, and Crushed Stone), which are widely used in earthwork projects in certain parts of Turkey and Northern Cyprus.

Geotechnical rock-mass evaluation of the Anamur dam site, Turkey
Ozsan, A; Karpuz, Celal (Elsevier BV, 1996-03-01)
This paper describes a feasibility-level geotechnical evaluation carried out at Anamur dam site, in terms of stability analysis of dam foundation, excavation slopes and a diversion tunnel. The proposed Anamur dam will be built across the Anamur river on the Alanya metamorphic series which consists of phyllite, schist and slate units at the site. Geotechnical investigations included drilling for core, pumping tests, sampling for laboratory testing, and a detailed discontinuity survey.
Thermal and salt crystallization effects on marble deterioration: Examples from Western Anatolia, Turkey
Yavuz, A. B.; Topal, Tamer (Elsevier BV, 2007-03-09)
Six commercially available and extensively used Turkish marbles having different textural properties were subjected to ageing tests in order to assess their resistance against salt crystallization with thermal effect. The change in physico-mechanical properties of the marbles including weight, dry unit weight, effective porosity, water absorption, dry and saturated sonic velocities, uniaxial compressive strength (UCS), indirect (brazilian) tensile strength, flexural strength, abrasion value, and impact resi...
Design of anchorage and assessment of the stability of openings in silty, sandy limestone: a case study in Turkey
Akgün, Haluk (Elsevier BV, 2004-01-01)
This study presents a procedure for the design of anchorage and for the assessment of the stability of openings in silty, sandy limestone through investigating the geotechnical problems of the Hasankeyf historical settlement area in southeastern Turkey, of which a good portion will stay below the reservoir of the proposed Ilisu dam. Rock mass characterization was performed. The RMR and GSI methods were utilized for rock mass classification. The RocLab software was used to determine the shear strength parame...
Strength of sands in wedge shear, triaxial shear, and shear box tests
Mirata, Tuerker; Erzin, Yusuf (ASTM International, 2007-03-01)
Limited tests had indicated peak drained values of angle of internal friction (of gravelly sands measured in the cylindrical wedge shear test (cylwest) to be relatively closer to the (expected from plane strain tests than from triaxial tests. Such a difference was not obtained between the results of the prismatic wedge shear test (priswest) and the triaxial test on gravels and crushed rock. In this study, six sands with <3.35 mm particles were tested. It was seen that the main reason for the difference betw...
Support capacity estimation of a diversion tunnel in weak rock
Ozsan, A; Basarir, H (Elsevier BV, 2003-03-01)
This paper presents the results of the support capacity estimation for the diversion tunnel of the Urus dam site in highly weathered tuff and weak zone. Tunneling in weak rock requires some special considerations, since misjudgment in support design results in costly failures. There are several ways of estimating rock support pressure and selecting support. However, all systems suffer from their characteristic limitations in achieving objectives. Thus, it is more useful to use different methods for estimati...
