Abstract

Landslides occur almost every year in Malaysia, especially during rainy season. Massive landslides can cause extensive damage and fatalities. An investigation has been carried out on two (2) landslides in Kuala Lumpur at two (2) different geological formations known as Kenny Hill and Hawthornden Schist. Kuala Lumpur, located at the southwest part of Peninsular Malaysia is covered by flat and hilly terrain. In the tropical region such as Kuala Lumpur most of the landslides were associated with residual soils. The purposes of the present study are therefore to examine the engineering properties of residual soil as input for slope stability analysis, to develop models of slope stability of failed soil slopes at Bukit Aman and adjacent slopes of Puncak Setiawangsa, to identify the causal factor contributing to the landslides and to recommend suitable rectification works. A well-established computer program 'SLOPE/W' developed by GEOSLOPE was deployed by adopting a limit equilibrium method (LEM) to determine the factor of safety (FOS) for the slopes. Based on the results, the FOS were less than 1.5 signify the inherently unstable slopes. In regard to the investigation, the failure at Bukit Aman can be classified as a shallow failure while in the case of the adjacent slopes of Puncak Setiawangsa, a catastrophic landslide could happen if the slopes strengthening structures, "pre-stress ground anchors" lose their holding capacity. The landslides in these study areas may be attributed to a combination of several factors such as steep slope, lack of drainage system, erosion and lack of ground anchors maintenance.
