ABSTRACT: The first area is rock instability
in conglomerates walls, and the second area is soil instability in a slope composed
of sand gravel and shale in the south of the study area. In the first area,
rock slopes were studied by fractures condition, slope morphology, measured
engineering features of rocks, and then interpreted by Dips software to define
the fracture types for analysis of block toppling. The rock slope of the area
was modeled by Rock plan by adding water penetration and earthquake. The
results showed that in dry condition these slopes were stable, but by penetrating water and
saturation of the open spaces of the fractures, the block toppling will occur. Also, seismic activities in the
area caused the instability of the slopes, and landslide will happen. In the
second area, landslides were spoon-shaped type. To investigate the soil slope
stability, the condition of slope was modeled by using soil engineering
properties and measuring the morphological condition of the slope such as slope
dip, layers thickness, layers dip and slope elevation. It was shown instability
of the soil slopes. To stabilize the sliding areas, the dip changing method and
formation of stepped-style slope were done. However, the new condition changed the formation of sliding areas in the
upper most part of the stairs. The retaining walls formed from the local materials
were applied to the slope to provide the desire stability.
