dc.description.abstractThis paper presents the determination of the parameters of a nonlinear elastic model from the analysis of the results of a pressuremeter tests. In order to identify the best set of parameters of the model was necessary to simulate the finite element method, define an objective function corresponding to the difference between the results measured in the field and obtained numerically and finally, to use a genetic optimization algorithm. For the estimation of the initial populations of the algorithm, it was proposed the delimitation of a search space that uses model parameters obtained with triaxial tests. It was concluded that the genetic algorithm was efficient in the back analysis of the studied pressuremeter curves.pt_BR

dc.description.resumoEste artigo apresenta a determinação dos parâmetros de um modelo elástico não linear a partir da análise dos resultados de ensaios pressiométricos. Para identificar o melhor conjunto de parâmetros do modelo foi necessário simular o ensaio com o método dos elementos finitos, definir uma função objetivo correspondente à diferença entre os resultados medidos no campo e obtidos numericamente e, por último, usar um algoritmo genético de otimização. Para a estimativa das populações iniciais do algoritmo, foi proposta a delimitação de um espaço de busca que utiliza parâmetros do modelo obtidos com ensaios triaxiais. Concluiu-se que o algoritmo genético se mostrou eficiente na retroanálise das curvas pressiométricas estudadas.

INVERSE ANALYSIS OF A PRESSUREMETER TEST CURVE USING A HIPERBOLIC MODEL ABSTRACT This paper presents the determination of the parameters of a nonlinear elastic model from the analysis of the results of a pressuremeter tests. In order to identify the best set of parameters of the model was necessary to simulate the finite element method, define an objective function corresponding to the difference between the results measured in the field and obtained numerically and finally, to use a genetic optimization algorithm. For the estimation of the initial populations of the algorithm, it was proposed the delimitation of a search space that uses model parameters obtained with triaxial tests. It was concluded that the genetic algorithm was efficient in the back analysis of the studied pressuremeter curves.
