| Summary: | Aim of the study:
The paper presents results of tests and calculations aiming at the determination of the influence of changes in the values of municipal waste cohesion on the values of safety factor calculated with the Fellenius method. The works in questions were performed for the landfill for waste other than hazardous and inert waste located in Jasło.
Material and methods:
The analysis was based on our own research, calculations and the existing landfill documentation. The computational part of our work included checking the stability of slopes in two selected cross-sections, assuming municipal waste cohesion values in the range of 0–30 kPa. Depending on the assumed cross-section and the calculation scheme, we concluded that even for cohesion equal to 23 kPa the calculated safety factor is indicative of stability deficiencies.
Results and conclusions:
On the basis of geotechnical parameters compliant with the standard, we checked the stability of the slope in a selected cross-section. For the analysed cross-section we obtained safety factor values in the range of 0.70-1.38, thus proving the dominance of retention forces. |
