Análisis técnico y económico al utilizar suelos cohesivos estables como relleno tras muros de contención

Abstract

Abstract: A comparative analysis has been done between geotechnical designs of cantilever retaining walls with imported granular backfill and in situ cohesive backfill. Classic lateral earth pressure has been used to calculate static forces and pseudo-static analysis for seismic forces.This analysis is based on the expected flexibility of the wall as recommend by german normative DIN (Deutsches Institut für Normung), which states that percentages combinations of active and at-rest lateral earth pressure mustbe used to calculate the forces. Moreover, diverse authors criteria have been used to establish limits tousecohesion and soil-wall frictionparameters. Finally, comparative cost analysis has been done of all the wall s constructionbased on those more representative items, as a result, the expensive design was the wall with imported granular backfill, nevertheless,this is conditioned by the availability of the granular materials in the zone.
