Interação onda-solo marinho, análise de sensibilidade, planejamento de experimentosResumen
Os fenômenos associados à interação dinâmica entre ondas e leitos marinhos porosos são objeto de intensas pesquisas ao redor do mundo. O assunto é de extrema importância para a análise da estabilidade de estruturas portuárias e offshore, dutos e taludes submarinos, por exemplo. Neste trabalho, foi conduzida uma análise de sensibilidade de um modelo analítico para representação das tensões, poropressão e deslocamentos induzidos por ondas em leitos marinhos porosos. A análise de sensibilidade foi realizada aplicando-se o método de Taguchi para planejamento de experimentos, em conjunto com uma análise de variância (ANOVA). Foi possível identificar os parâmetros do solo que mais influenciam na resposta do modelo analítico. Foi realizada ainda a otimização dos fatores do modelo analítico a fim de determinar os parâmetros ótimos para um conjunto de dados experimentais analisados.
