Análise de contenções flexíveis atirantadas: estudo de caso: metrô de Curitiba

Abstract

This paper presents an analysis of security and stability of flexible retaining systems through the case study of the deployment of the subway at Curitiba. Grounded in a strong theoretical framework on soil mechanics and geotechnical information on Formation Guabirotuba, main geological base soil of Curitiba, the study provides an evaluation of the retaining structure foreseen in the pre-project presented by the Institute for Research and Urban Planning of Curitiba to companies applying to the bidding process for the realization of the design and subsequent building of this mean of transportation. With prior knowledge of the specific soil characteristics of the region where the subway will be deployed a simulation was held of the stages of excavation that will be part of the construction process known as cut and cover and through the calculation made by the analysis of finite element methods with software was obtained result satisfactory to determine the validity of previously established parameters to select the retaining system method.
