PDFSteel sheet piles as measures against rapid mass flows
Steel sheet piles have been used for mitigation against small snow avalanches and rock falls for over twenty years in Iceland in areas with limited space for other types of mitigation measures at road sides. Those approx. 3 m high structures have proved to be useful and have resulted in fewer road closures. Little is known about the forces that avalanche or rock falls exert to these structures and it hampers further development. For this reason, the Icelandic Road and Coastal Administration (IRCA) and the Norwegian Geotechnical Institute (NGI) decided to instrument one such wall in north Iceland.
