Abstract

Noise barriers along railway tracks are exposed to frequent load changes, as a result of the strongly varying pressure field, induced by passing trains. Especially at high speed tracks the dynamic load effects can lead to heavy mechanical stress on the structure, due to the high and low pressure sections following each other directly. The deformation monitoring of noise barriers is usually realised with conventional sensors for the monitoring of supporting structures (accelerometers or inductive displacement sensors), which require a lot of installation effort. Furthermore, they are yielding only information at discrete measurement points. With the usage of a profile scanner, the installation effort can be reduced to a minimum, and it is possible to generate added value in information about the structure, due to its high profile wise spatial resolution. Compared to conventional sensors the profile scanner can generate qualitatively comparable results with less effort and therefore opens up new possibilities for the efficient monitoring of noise barriers.
