Rock slope Stability Assessment for Rock Cliffs at Tar Al-Sayyed Area (Karbala Governorate Middle of Iraq)

摘要: Tar Al-Sayyed area (a tourist area), locates in the west of Karbala Governorate-Middle of Iraq, it is characterized by a rock cliff with abundance of naturally-forming caves locally known as Al-Tar caves. Field studies revealed the abundance of rock slope failures, the dominant types are rock fall, secondary toppling, and local disintegration followed almost by rolling. Slope stability assessment was carried out by stereographic projection. Secondary toppling mechanisms (generally due to the effects of differential weathering and\or erosion, and undercutting) include multidirectional toppling, tension crack toppling and toppling & slumping mechanisms. Some treatment measures are proposed to stabilize the slopes and protect the visitors in the area.
