Slope stability analysis of al-Qadhi cliff in al-Qadissiya, Iraq

الملخص EN

Field studies of the (Subhorizontal-layer) slopes of Al-Qadhi area, central Iraq, revealed the abundance of rock slope failures, the dominant types are rock fall, secondary toppling, and 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 and slumping mechanism.

Some measures are proposed to stabilize the slopes including removal of blocks liable to toppling in the critical cases, and filling the undercut slope toe by convenient soil with binding materials in the less critical slopes.
