Stability and permanent displacements analysis of wasteland during earthquakes

IntroductionStability of municipal solid waste (MSW) was not a major concern early because waste instability was considered as an operational problem that can be remedied by replacing the waste in its original position. However, with the introduction of liners and leachate collection and removal systems (LCRS), the integrity of the liner and LCRS may be concerned. Instability or displacement of a wasteland may result in failure of above system and contamination of groundwater or surface wa…

Stability and permanent displacements analysis of wasteland during earthquakes

According to the results of experiments on the municipal solid waste (MSW), a series of formula are deduced to calculate the leachate free-faced headline curve. By means of static and dynamic finite element method (FEM), the stability of a wasteland during earthquakes is analyzed. It is demonstrated that the positions of the most dangerous sliding surfaces during earthquakes are fairly stable. Based on the above findings, this paper developed the Newmark method by increasing the precision to reckon the permanent deformation of wastelands during earthquakes. The method presented in the paper is not only of great importance to instruct the anti-seismic design of wasteland, but also valuable to the design of ordinary dams and embankments.
