Abstract

The instability of rock slopes controlling the main Arbil-Sulaimaniya road has been studied in the southwestern side of Haibat Sultan Mountain, northern Iraq. The cause of this instability is the presence of road cuts as well as the erosion at the toe of the slope. The military operations in the area have further increased the hazardous condition of the slope. Field observations at ten stations have revealed that plane sliding of limestone slabs had occurred within the layers of friable marl. The study focused on the mode of failure, as affected by slope orientation and discontinuity geometry. Subsequent monitoring revealed continued hazardous sliding and some disastrous incidents have also occurred. As a result of the rock slope analysis, remedial measures have been proposed to stabilize the slope.

Rock Slides Along Haibat Sultan Road, N. Iraq
