Assessment of physical vulnerability to landfill failure-taking Shenzhen as an example

Abstract

Municipal solid waste (MSW) have increased in the accumulation rate in China and landfill is the most common method of MSW disposal management. A landfill failure occurs when the great majority of rocks, soil materials or debris flows move down from a slope due to gravity. The physical vulnerability of the catastrophic landfill failure occurred in Shenzhen 2015 is analyzed in this paper. It deduced that the vulnerability would increase with the impact pressure and maximum bending moment of each building. Typical deformation characteristics of affected buildings, such as bending moment and shear force are simulated using ETABS to determine whether the building will collapse after the impact of the landfill failure. A vulnerability curve indicates the relationship between impact pressure of the landfill failure, the building type, building use and the damage degree of the building.
