Abstract

Geological mapping is a work that transfers field data into a base map. It is also a basic approach in studying rock slope stability as it studies lithology and geological structures of rock slope. The slope stability has become the most concerned issue throughout the years as it causes endangerment and economic risks to humans. Malaysia has high intensity of rainfall. This causes high weathering rate in rocks, which in tum increase the probability of occurrence of landslide and rock slide. So far, detailed geological mapping and analysis of rock slope stability have not been carried out in study area. In this study, study area was studied in terms of geomorphology, stratigraphy and structural geology and a geological map of study area was produced in a scale of l: 25,000. In the context of geomorphology, study area comprised of hill unit only and it was subjected to all types of weathering processes. Its drain age system showed dendritic pattern and divided study area into three watershed regions. Seven places of mass movement were found. In the context of stratigraphy, study area comprised of slate unit, shale unit and limestone unit and its depositional environment was shallow marine in general. In the context of structural geology, lineament analysis was done. Folds, faults, joints, cleavages and veins were determined. In rock slope stability analysis, quality of rock masses of three rock slopes were first studied by using RMR system. Rock slope 1, 2 and 3 had ratings of 57, 59 and 67 respectively. Thus, their rock masses were classified as class number III, III and II accordingly. Then, their stability were analyzed by using kinematic analysis was found to be generally stable but some small blocks might break off from rock slope 1 and 2. Thus, no further analysis were required.
