Abstract(s)
A construção de pontes sofreu melhoramentos ao longo do tempo, mas ainda continuam a ocorrer acidentes durante a construção. De facto, como se demonstra neste trabalho, muitos desses colapsos ocorrem na fase construtiva.
Apresenta-se neste trabalho, para além de uma visão geral dos processos construtivos, uma síntese de um número significativo de acidentes ocorridos durante a construção. Enfatiza-se as lições aprendidas com esses acidentes.
Apresenta-se também uma síntese das disposições constantes nos Eurocódigos relacionados com a verificação da segurança durante a construção, incluindo as ações a considerar e a sua quantificação.
Por fim, é apresentado um caso de estudo no qual a segurança na fase construtiva assumiu particular importância. Acerca da ponte estudada – Ponte Internacional de Quintanilha – construída por avanços sucessivos – houve necessidade de conceber um conjunto de cabos exteriores com a finalidade de garantir a segurança face a um cenário de queda de carro de avanços e respectiva aduela.
Abstract: The construction of bridges has undergone improvements over time, but the accidents still continue to occur during construction. In fact, as i tis demonstrated in this work, many of these breakdowns occur in the constructive phase. I tis presented in this work, besides na overview of the constructive processes, a summary of a significant number of accidents occurred during construction. I tis emphasized the lessons learned from these accidents. I tis also presented a summary of the dispositions contained in the Eurocodes related to the verification of safety during construction, including actions to consider and its quantification. Finally, a case of study is presented in wich, security in the construction phase assumed particular importance. About studies bridge – Quintanilha International Bridge – built by balanced cantilever method – there was a need to devise a set of external cables in order to ensure safety against the scenario of traveller fall of advances and their segment.
