Landslides are frequent events that may affect the stability of structures as well as people’s lives. Every year, thousands lose their lives to landslides and countless homes and structures are damaged or destroyed. On February 2, 2024, a landslide involving several hundred cubic meters of debris triggered the descent of large rocks, measuring between 50 and 200 cubic meters, down the slopes of the Vevey valley in Switzerland. This rockslide impacted the A9 Lausanne-Saint-Maurice national road and bridge which consists of two identical composite steel and prestressed concrete bridges. The landslide damaged part of the 1969 Veveyse bridge that accommodates around 61,000 vehicles daily before the massive rock came to rest near the bridge’s foundation. Fortunately, there were no casualties, and nearby homes were unaffected. Following the incident, field investigations were carried out to collect data on the rockslide’s trajectory and the extent of the bridge’s damage. Given the region’s propensity for natural erosion and frequent rockslides, a finite element study using Abaqus was undertaken to analyze the bridge’s behavior under various rockslide scenarios. The study examined the effect of impact forces and bridge response by considering different impact scenarios. The results indicate that the impact force from rockfall is characterized by a brief impulse that causes intense vibration of the bridge and important reactions on its supports affecting the safety of the structure and vehicles moving on the bridge.
