Reporter: Doctor Fan Linfeng

Work unit: Southern University of Science and Technology

Time: 16:00-17:00 pm, Friday, January 10, 2020

Location: Room 211, State Key Laboratory of Geohazard Prevention and Geoenvironment Protection (the opposite side of Gongtong Yuan)

Report abstract:

Rainfall landslide is a common natural disaster in mountainous areas, which the inducing process is the result of soil and water interaction in the rainfall. This paper mainly introduces the LHT-Perla, the watershed scale rainfall landslide occurrence and migration model coupled with the hydrology and soil mechanics of the slope, and the real-time evaluation system for the risk of rainfall landslide based on the model. By using the simulation evaluation system, it explains the influence mechanism of slope force history, spatial heterogeneity of physical and mechanical properties of soil and dynamic change of rainfall on the occurrence, development and dangerous dynamic evolution of landslide. Finally, the influence of landslide on river sediment fluxes in mountainous area is preliminarily quantified under the framework of geomorphic process evolution. The research results have deepened the understanding of the hydro-mechanical inducing mechanism of rainfall landslide and its relationship with the evolution of mountain topography.
