The "9.5" Luding earthquake induced extensive coseismic geological hazards in the Hailuogou Scenic Area at the epicenter, with 50% of the scenic area roads located within the seismic intensity IX (9-degree) impact zone, resulting in severe road damage and complete loss of traffic capacity. To invest…

Efficient design of flexible rockfall guiding nets requires a clear understanding of how slope topography influences rockfall energy dissipation and system loads, a task often hindered by the computational cost of conventional models. To this end, this study first developed, calibrated, and validate…

Deep strata of coarse-grained Soil-Rock Mixture (SRM) are widely distributed in southwestern China, posing a serious threat to construction and operational safety due to their loose structure, high porosity, and abundant rock blocks. Tunnel excavation in such deep-buried, fractured, and highly heter…

The complex deformation behavior of landslides can be described by the three-stage deformation curve of geotechnical materials, providing an effective phenomenological tool for early warning and prediction. However, to date, the physical mechanism underlying the three-stage deformation of landslides…
