Abstract

Sustainable approach towards an open dumping area can be determined by predicting the long-term settlement of waste soil. To predict the settlement that happens in closed open dumping area in Bukit Palong, Lukut in the state of Negeri Sembilan, Malaysia, the Power Creep Function is used. The waste soil were collected to determine their basic geotechnical properties by doing sieve analysis, Atterberg Limit, consolidation, compaction and direct shear. From the geotechnical properties of the waste soil, the Power Creep Function are be used to determine the long-term settlement of the reused dumping area. There are three case studies and one of the parameters is M' or reference compressibility that have the value from 1.6 × 10-5 to 5.8 × 10-5 kPa. There is also N' or rate of compression that have value from 0.50 to 0.67. In Case 1, M' and N' are constant which are 5.8 × 10-5 kPa and 0.67 respectively. Case 2 have the value of M' increased from 1.6 × 10-5 to 5.8 × 10-5 kPa with respect to age while N' constant at 0.5. Lastly the Case 3 shows the M' is constant at 1.6 × 10-5 kPa while the N' is increased ranged from 0.50 to 0.67 with respect to age. The area will reach a stable condition which means the settlement has stabilized after 50 years. From the three case studies, the analysis show that the settlement does not exceed the allowable settlement which is 0.05m every year.
