ABSTRACT
The paper presents the stability reinforcement solutions on the two old large embankment type sanitary landfills localised nearby Warsaw, i.e. Radiowo and Lubna. The methods consist of retaining wall, berms, geogrids and tyre mattress. The paper also presents shear strength parameters determined for different kinds of wastes disposed on a.m. landfills as well as stability analysis of the landfill slopes by classical (Swedish and Bishop’s) and finite element methods (FEM). Field investigations consisting of morphological analysis, settlement measurements, WST and CPT sounding, back analysis as well as slope failure tests were carried out for determination of parameters.
