Em Portugal serão construídas, nos próximos anos, algumas centenas de quilómetros de vias férreas de alta velocidade. Em diversos países tem-se verificado que a conjugação de velocidades elevadas de circulação com determinadas características dos solos de fundação conduz a fenómenos de amplificação dinâmica das deformações resultantes da circulação dos comboios. As linhas de alta velocidade, em Portugal, terão inevitavelmente de atravessar zonas onde a velocidade de circulação se pode associar com as condições desfavoráveis das fundações criando os fenómenos dinâmicos referidos. O presente artigo apresenta a pro ble - má tica da geração de vibrações devidas à circulação de comboios, uma revisão sucinta de alguns métodos exis tentes para a previsão e análise do fenómeno e analisa as medidas de mitigação existentes.
