| Abstract | ||
| Engineering geological study was carried out to evaluate the slope stability of a road cut in a tourism area, north of Sulaimaniya Governorate. The study involved geotechnical evaluation of the area including engineering and petrophysical tests. Two formations are exposed in the studied area, Cretaceous in age. These are Kometan and Balambo formations, both of them consist mainly of bedded limestone. The area is affected by tectonic uplift due to Alpine Orogeny, forming two set of joints of NE – SW and NW – SE directions. For the first time, direct shear test is introduced to get the most important parameters concerning slope stability (cohesion and friction angle). For station No.(1) sliding is more possible along planes of tectonic joints (J1), while that of station No.(2) sliding is along bedding planes. Both slopes are considered unstable, where planner sliding is dominant especially in the second station. | ||
