Colunas de brita no melhoramento de solos moles

Abstract

O presente trabalho, tem como objectivo o estudo e a aplicação da técnica de melhoramento de solos por colunas de brita, focando alguns aspectos práticos do dimensionamento, nomeadamente no que diz respeito à aplicação do método observacional. Apresentam-se casos concretos de estudo e respectivo dimensionamento, em particular a aplicação de um caso de estudo em que houve tratamento com colunas de brita de solos moles. Foi apresentado e testado, aparentemente com sucesso, o método observacional desenvolvido por Asaoka, que poderá representar uma importante ferramenta de apoio à decisão e ao projecto no caso de trabalhos em solos de difícil caracterização, especialmente se utilizada em conjunto com o modelo desenvolvido pelo Plaxis para determinar assentamentos de consolidação secundária.

The major goal of this work is the study of the soil Improvement technique by stone columns, detailing some practical aspects regarding to design, namely in what concerns to Observational Method. One real case is presented, with stone columns design on soft soils included. It was presented and tested, apparently with success, the observational method developed by Asaoka, which can represent an important help decision tool in cases were the soils are difficult to model, specially if used simultaneously with the Soft Soil Creep Model developed by Plaxis to study Fluency settlements.
