Abstract

Abstract

With the increasing development of unmanned aerial vehicle technology, unmanned aerial vehicle remote sensing (UAVRS) has been widely used in the risk analysis of geological hazards. However, the quantitative risk analysis method of landslide hazards based on that technique has still being developed up to now. A three-dimensional geometric model of slopes based on the laser point cloud data collected by UAVRS was built, the failure probability of the slope was appraised by the first-order reliability method, the safety factors of the slope were calculated by the numerical simulation software of FLAC3D, the failure consequences of the slope were determined based on the secondary development of FLAC3D, and the quantitative risk analysis on a single landslide hazard was conducted. The proposed analysis method was simple and straightforward, which provided a new idea for assessment risks of landslide hazards.
