چکیده مقاله:
In this study, a geotechnical investigation consisting of static and dynamic landfill covers analyses was conducted on Nazlou landfill in West-Azerbaijan province, Iran. All the analyses were performed for the landfill cover at the end of construction. To obtain more realistic results, the physical and mechanical properties of the buried wastes were considered to be variable with depth. These properties were determined either by field investigation or from the data in the literature. A Newark-type dynamic analysis was conducted to calculate the permanent displacement of the covers. Having the properties of the buried wastes, the earthquake records whose response spectrum have a better match to the site design spectrum were selected. In the Newmark analyses, the sliding of both the critical wedge and the landfill cover was investigated. Consequently,the yield acceleration and the time history of permanent displacements were evaluated. Finally, the analyses results were used to assess the static and seismic stability of the landfill and the suitability of the design liner. The project site is located near the village of Nazlou, at the northwest of Urmia County in West Azerbaijan province, Iran.As shown in Figure 1, the site is positioned on the heights overlooking the village of Nazlou at the end of Urmia sero Road.
