This makes possible to track the load history of a structure since the fiber is placed. To verify that the tunnel is not structurally affected during the construction period, sections of it are instrumented and the micro deformations that occur are measured, which are compared with those of the model. It has been possible to appreciate the ovalizations and tensions in the vault during the different phases of the construction process, all of them being below the limit values established in the contingency plan. This technique has made possible to validate the works carried out throughout the process.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo É discutido o exemplo de um caso real em que, em um túnel existente, um edifício é construído com instrumentação de fibra ótica que permite monitorar o histórico de carregamento de uma estrutura desde sua instalação. Para verificar se o túnel não é estruturalmente afetado durante o período de construção, trechos do túnel são instrumentados e as microdeformações ocorridas são medidas, as quais são comparadas com as do modelo. Foi possível apreciar as ovalizações e tensões na abóbada durante as diferentes fases do processo de construção, estando todas abaixo dos valores limites estabelecidos no plano de contingência. Esta técnica permitiu validar os trabalhos realizados ao longo do processo.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Se discute el ejemplo de un caso real en el que, sobre un túnel existente que se instrumenta con fibra óptica, se construye un edificio. Ello permite hacer el seguimiento de la historia de cargas de una estructura desde que se coloca la fibra óptica. Para constatar que no se ve afectado estructuralmente el túnel durante el período de construcción, se instrumentan secciones del mismo y se miden las microdeformaciones que se producen, que se comparan con las del modelo. Se han podido apreciar las ovalizaciones y tensiones en la bóveda durante las distintas fases del proceso constructivo, estando todas ellas por debajo de los valores límites establecidos en el plan de contingencias. Esta técnica ha permitido validar durante todo el proceso las obras realizadas.]]></p></abstract>
