To the Calculation of the Stability of Embarkment from Bottom Ash and Solid Municipal Waste

Abstract

During the construction of solid municipal waste landfill-sites one of the main objectives is to secure establishment of watertight landfill bottom of the screen, to prevent contamination of groundwatersd by leachate. It was offered to perform such screen from ash concrete produced from hardening high calc ash of Kansk-Achinsk coal basin. After considering the results of the test series of samples from ash concrete was set its brand M100. Concrete class Bf 7.5 strength, brand by density D1100. Such strength in combination with the previously studied low permeability is sufficient for estyablishment of watertight screen. This technology is based on joint storage of bottom ash waste (BAW) and solid municipal waste (SMW). For substantiation the stability of ermbarkment slope from BAW and SMW at various of its founding were calculated stability analysis by the method of flat sliding surfaces. There was found that the shelf life of SMW and its gradual seal has a popsitive effect on the stability of embarkment. The stability of layered embarkment erected on the proposed technology encures even when founding the slope 1:1.
