Commonly a number of different gravity driven hazards (shallow landslide, rock slide, rockfall, small snow slides) will act at same location, threatening the safety of people, buildings and infrastructure. In this case protection barriers have to be designed to cope with the different load cases of multiple natural hazards (Fig. 77.1). The following covers the design challenges of a barrier project in Baltisberg, Switzerland, to protect a railway from both shallow landslides and rockfalls. Each hazard presents a greatly differing load case. Shallow landslides impact with spreading pressures loading gradually, while rockfalls impact punctually with high velocities. Findings from a number of full scale barrier tests and a finite element simulation software FARO used in the design of flexible wire protection systems are presented.
