Abstract

PROCESSO PARA LOCALIZAR E MEDIR AS DEFORMAçõES DE UMA OBRA DE ENGENHARIA CIVIL A invenção se refere a um processo para localizar e medir as deformações de uma obra de engenharia civil, caracterizado pelo fato de nós aplicarmos na dita obra ou sob o dita obra pelo menos um geossintético (1) equipado com uma pluralidade de fibras óticas (2a à 2e) paralelas e capazes de transmitir os sinais, as ditas fibras óticas compreendendo redes de Bragg (3), regularmente espaçadas e distribuídas em séries (4) de NI redes consecutivas correspondentes ao mesmo comprimento de onda, as ditas séries sendo elas mesmas distribuidas em conjuntos idênticos compreendendo cada um N2 séries consecutivas correspondentes aos comprimentos de onda diferentes, e pelo fato de que em pelo menos duas fibras óticas, os números N1 de redes de uma série e os números N2 de séries (4) de um conjunto (5) são determinados de tal forma que a medida dos afastamentos entre os comprimentos de onda da luz incidente enviada em cada uma das ditas fibras óticas e os comprimentos de onda da luz refletida pelas redes de Bragg permitem, por um lado, localizar as deformações sofridas pela obra e, por outro lado, medir as elongações das ditas fibras óticas no local das deformações.
