Universiti Technologi Malaysia, Faculty of Civil Engineering. AbstractLandslide occurrences had caused failure of sheet pile wall located about 6 m from Bangunan Tambahan, Fakulti Kejuruteraan Mekanikal (FKM), Universiti Teknologi Malaysia in Skudai, Johor. With the aim of investigating cause(s) of the failure, the slope stability conditions prior and after construction were simulated using SLOPE/W Version 3.03. The results showed that effects of load of a newly filled water tank sited on the top of slope contributed to subsident of the slope surface within the vicinity by creating tension cracks near its raft footing. The slope became more unstable as the soil moisture or pore-water pressure increased due to infiltration of rainwater. This has reduced the shear strength, in particular the cohesion value, c. The simulation also confirmed the hyphothesis that the global soil mass movement started from the hill top where the water tank was located toward the installed sheet pile. The combined mobilized shear force and lateral pressure of the global slope was about 8 times the strength of the sheet pile. The associated stresses are found to be related to the formation of the heave pushing up the soil at the toe of slope and soil under the road pavement adjacent to the new laboratory buildings.
Kejadian tanah runtuh telah mengakibatkan kegagalan dinding cerucuk keping yang terletak 6 m dari Bangunan Tambahan, Fakulti Kejuruteraan Mekanikal (FKM), Universiti Teknologi Malaysia Skudai, Johor. Penyiasatan bagi mencari punca-punca kegagalan dilakukan dengan kaedah simulasi komputer menggunakan SLOPE/W Versi 3.03 untuk keadaan tapak sebelum dan selepas pembinaan siap. Hasil simulasi menunjukkan bahawa pengaruh beban tangki air baru yang terletak di puncak cerun adalah penyumbang kepada kejadian enapan di sekitar permukaan cerun dengan kewujudan retak tegangan berdekatan asas rakit tangki air tersebut. Ketidakstabilan cerun didapati bertambah dengan pertambahan kandungan lembapan atau tekanan air liang akibat penyusupan air hujan menyebabkan pengurangan kekuatan riceh tanah terutamanya pada tegasan jelekitan, c. Simulasi juga menunjukkan pergerakan jisim tanah secara global bermula dari kedudukan tangki air di puncak cerun menghala dinding cerucuk keping di kaki cerun menghasilkan paduan daya riceh dan tegasan melintang yang bergerak pada keupayaan 8 kali ganda daripada kekuatan sebenar cerucuk keping. Paduan daya ini juga didapati berkaitan dengan kejadian lambung yang menolak ke atas tanah di kaki cerun dan di bawah permukaan jalan berdekatan bangunan-bangunan makmal yang baru. | Item Type: | Journal |
