الملخص الإنجليزي

In this research a detailed geotechnical study was carried out on the rock slopes at Tar Al-Sayyed cliff - Karbala Governorate, at 30 Km west of Karbala city - middle of Iraq, where both of Injana and Dibdibba Formations are exposed.

The research covers several aspects; it includes collection of field information from unstable rock slopes at (23) stations representing all the rock failure types that happened or likely to happen.

In each station rock slopes are completely surveyed; also the rocks are described in an engineering way and a complete discontinuity survey is carried out according to Anon (1972;1977) and their relationship with the rock failure is established.

Some soil tests are also carried out for remoulded samples of claystone layers in the study area.

At the end all factors affecting the stability of the slopes have been evaluated.

The field study shows that rock failures have high density and include (from the most to the least abundant) toppling (mostly in secondary type), rock fall and granular disintegration of some friable sandstone and claystone layers.

After evaluating all the factors affecting the stability of the slopes, it becomes obvious that the causes behind rock failure are mainly effects of weathering or differential erosion as well as the discontinuities surrounding the rock mass and steep slopes.

A landslide hazard map for the study area is constructed at a scale (1:7000), for the first time depending on ten factors according to landslide possibility index system (LPI) value to assess the hazards of (70) sites in the area.

Hazards in the area are classified into three categories (no hazard, moderate hazard and high hazard).

Some remedial measures are proposed to protect Maqam Al-Qattara building, visitors and roads close to the unstable slopes, such as construction of retaining wall, use of gabions, use of wire mesh and removal of unstable masses.
