Ca' Rossa landfill is located in the southern part of the Venice lagoon. Transfer of MSW into the landfill has been over since 2009. The management company has been waiting for the development of further waste settlements, before providing for the final cover system. This paper presents an analysis of settlements due to compressibility of natural soils, underlying the landfill, and of wastes. The study was carried out through analytical and numerical methods using as input data periodic topographic levelling of the landfill and geotechnical parameters of soils, derived from previous laboratory and in-situ tests. By comparing expected and actual settlements, a calibration of the original input data was possible. These corrected values were finally implemented in a finite element model in order to estimate the future landfill settlements.

Abstract
Ca' Rossa landfill is located in the southern part of the Venice lagoon. Transfer of MSW into the landfill has been over since 2009. The management company has been waiting for the development of further waste settlements, before providing for the final cover system. This paper presents an analysis of settlements due to compressibility of natural soils, underlying the landfill, and of wastes. The study was carried out through analytical and numerical methods using as input data periodic topographic levelling of the landfill and geotechnical parameters of soils, derived from previous laboratory and in-situ tests. By comparing expected and actual settlements, a calibration of the original input data was possible. These corrected values were finally implemented in a finite element model in order to estimate the future landfill settlements.Pubblicazioni consigliate
