1D and 2D Dynamic Site Response of Landfill Site Through Numerical Analysis

Solid waste management and disposal become a challenge on global level. Due to this rapid growth of waste, we are losing low-lying areas and valuable lands. Therefore, it is a peak demand to utilize the waste-filled areas for future use. The objective of this study is to get the dynamic response of a landfill site by using already available data in past studies. The response study of landfill site helps to predict the deformation and amplification behavior of the MSW fill sites. So that required preventive measures and ground improvement techniques can be implemented according to the response of site. The study area used in this paper includes landfill sites of Delhi area, which are mostly designed for about 20 m but now they are overfilled with more than 50 m. The aim is to find the seismic response of the site under defined dynamic loading. The response of landfill site was numerically analyzed both in one and two dimensions with the help of Cyclic1D and Plaxis2D software, respectively. The analysis performed is based on finite element method under the earthquake of magnitude of 6.5 with duration of 39.9 s and PGA of 0.3 g.
