Numerically based design of protection systems against landslides. Workshop Numeric in Geotechnology

fast flow-like landslides are the one of the most dangerous natural hazards. Rigid or flexible structures are often used to stop, deviate or slow down the flow. Because of the complexity of the landslide-barrier interaction, the design of these defence structures is still based on oversimplified and empirical approaches. Numerical methods able to cap-ture the essential features of the phenomenon can offer a valuable tool to gain a better understanding of the impact process and to support the design. This paper shows the potentialities of the MPM in this field. The run-up of the landslide and the dynamic forces on the structure are some of the fundamental parameters to define the properties of the barrier.
