Continuous rigid-frame bridges across valleys are often at risk of rockfalls caused by heavy rainfalls, earthquakes, and debris flow in a mountainous environment. Hollow thin-walled bridge piers (HTWBP) exposed to the threat impact from accidental rockfalls. In current research, ANSYS/LS-DYNA is used establish high-precision rockfall-HTWBP model. The model verified against scaled test performed...

Rockfall constitutes a major threat to the safety and sustainability of transport corridors bordered by rocky cliffs. This research introduces new approach rockfall susceptibility modeling for identification potential source zones. is achieved developing data-driven model assess local slope morphological attributes with respect rock evolution processes. The ability address “where” more likely o...

Numerous rockfall incidents involving infrastructure damage and loss of life have been reported along roads in mountainous terrain. Previous studies used quantitative risk assessment approaches to identify the level risk. However, appropriate indicators that are able describe time-varying not yet developed. This study aims develop a mitigation method based on reliability concepts, classify data...

Windstorms represent one of the main large-scale disturbances that shape European landscape and influence its forest structure, so post-event restoration activities start to gain a major role in mountainous management. After disturbance event, biological legacies may enhance or maintain multiple ecosystem services mountain forests such as protection against natural hazards, biodiversity conserv...

Abstract Recent advances in remote sensing techniques and computer algorithms allow accurate, abundant, high-resolution geometric information retrieval for rock mass characterization from 3D point clouds. The automatic application of the extracted local scale rockfall susceptibility assessment, where discontinuities characteristics play a major role rocky slope stability, requires step by logic...

Current numerical schemes for 3D rockfall simulation are not able to correctly represent the stability properties of a freely rotating body. Here, we give proof using Lyapunov functions an extended intermediate axis theorem, which only involves angular momentum equations but also orientation Inspired by proof, present novel scheme respects body and can be incorporated in rigid bodies with frict...

Abstract. Many examples of rockfall simulation software provide great flexibility to the user at expense a hardly achievable parameter unification. With sensitive site-dependent parameters that are generalizable from literature and case studies, must properly calibrate simulations for desired site by performing back-calculation analyses. Thus, trajectory reconstruction methods needed. For purpo...

The scope of this paper is to summarize previous research pertaining the use digital elevation models (DEMs) and terrain (DTMs) in study rockfalls landslides. Research from 1983 2020 was surveyed order understand how spatial resolution DEMs DTMs affects landslide detection, validation, mapping. Another major question examined relationship between DEM extent rockfall or event. It emerged that, f...

Rockfall processes are now commonly studied through monitoring campaigns using repeat lidar scanning. Accordingly, several recent studies have evaluated how the temporal resolution of data collection and various data-processing decisions can influence apparent rockfall volumes estimated typical database creation workflows. However, there is a lack that consider quality associated volume estimat...

Rockfalls on debris slopes pose a significant hazard to canyon roads the Tibetan Plateau. In order assess risks and develop effective engineering solutions, it is crucial fully understand characteristics processes of rockfall movement. This research utilizes UAVs three-dimensional (3D) laser scanners capture images data, while Pix4D employed create high-precision 3D model from collected data. U...
