Abstract: One example of a hillside residential development that is of concern to the authorities is a rock slope off Jalan Kuari in Cheras. The rock slope was identified as being potentially unstable. The stability of this particular slope was critical because it was located immediately across the backlane behind a row of newly completed terrace houses. A study was undertaken to analyze the stability of the rock slope and to recommend suitable protection and/or stabilization measures, to ensure the long term stability of the rock slopes and the safety of the existing properties and human activities in the newly developed residential area. From this study, it was concluded that the rock slope behind the newly completed terrace houses is generally stable. Although all the joint planes are potential slip surfaces, no signs of major instability were found except for some localized small-scale unstable elements. Suitable protection measures and monitoring and maintenance programme were suggested to ensure the long term stability of the cut-slope.
Abstrak: Salah satu contoh pembangunan lereng bukit yang mendapat perhatian daripada pihak berkuasa ialah satu cerun potongan di Jalan Kuari, Cheras. Cerun potongan ini dikenal pasti mempunyai potensi untuk mengalami kegagalan. Kestabilan cerun potongan ini penting kerana ia terletak di belakang satu barisan rumah teres setingkat. Satu kajian kestabilan cerun itu telah dijalankan untuk mencadangkan langkah-langkah pemuliharaan cerun bagi menjamin keselamatan harta benda dan nyawa penduduk di situ. Dari kajian ini didapati batuan pada cerun berkenaan pada umumnya adalah stabil. Walaupun kesemua satah-satah ketakselanjaran yang terdapat mempunyai potensi menjadi satah-satah gelinciran, tiada tanda-tanda ketakstabilan major didapati kecuali unsur-unsur ketastabilan minor dan bersifat setempat. Beberapa langkah penjagaan dan pemantauan telah dicadangkan untuk memastikan kestabilan cerun potongan tersebut.
