| description | To analyze the stability of waste landfill, it is necessary to know the geotechnical characteristics of the solid waste material, especially the parameters that related to the stability calculation such as the strength parameters (cohesion and friction angle). The physical properties of the materials are also important, as well as the composition of the waste. This study conducts laboratory and field tests to obtained the aforementioned characteristics from a typical urban landfill in Indonesia. The case study is taken to be the TPST Bantargebang landfill. Due to the difficulties in obtaining undisturbed sample from waste landfill, the laboratory test was conducted using the artificial solid waste sample. Direct shear test was conducted to get the strength parameters of the artificial waste samples. Besides the laboratory test, field tests (cone penetration test, CPT & dynamic cone penetration test, DCPT) were also conducted on the closed landfill zones in TPST Bantargebang to obtain the typical bearing capacity of the fill materials. The results from direct shear test shows that the cohesion value of the waste material is in an agreement with the initial compression: higher compression results to higher cohesion, while the friction angle is in a contrary. The range of cohesion value is ranged between 0 to 41 kPa, and the range of friction angle is between 0 to 26°. The cone resistance value (qc) up to 10 m depth is in the range of 2 to 10 MPa. The equivalent CBR value from DCPT is ranged from 4% to 21%. Despite the large variability of bearing capacity at the top layers shown by the DCPT results, the CPT results in the field show that the bearing capacity (also the strength characteristics) of the waste materials is linearly increase along with the depth. |
