| Underpasses are very common in recent railway lines. Wild life corridors and drainage conducts often fall in this category of partially buried structures. Their dynamic behavior has received far less attention than other structures such as bridges but its high number makes that study an interesting challenge from the point of view of safety and savings. In this paper a complete study of a culvert, including on-site measurements as well as numerical modeling, will be presented. The structure belongs to the high speed railway line linking Segovia and Valladolid, in Spain. The line was opened to traffic in 2004. On site measurements have been performed in the structure recording the dynamic response at selected points of the structure during the passage of high speed trains at speeds ranging between 200 and 300km/h. By themselves the measurements provide not only reference values suitable for model fitting, but also a good insight into the main features of the dynamic behavior of the structure. In addition to it, finite element techniques will be used to model the dynamic behavior of the structure, representing its key features. This will allow further understanding of the dynamic response to the train loads. | |
