Abstract

The invention discloses a vulnerability assessment device of a landslide disaster-bearing body, which includes: a structural parameter acquisition module for acquiring structural parameters of the disaster-bearing body and establishing a finite element model of the disaster-bearing body; a stiffness calculation module for The finite element model conducts lateral inverted triangle distributed load analysis to calculate the overall lateral stiffness of the finite element model; the deformation simulation module is used to record the ultimate load when the finite element model collapses; the displacement calculation module is used to combine the impact energy with the finite In the case of equivalent bending deformation energy of the meta-model, the functional relationship between the horizontal load and the distance from the disaster-bearing body to the slope toe is obtained according to the calculation formula of the overall lateral stiffness and impact energy; the evaluation module is used to calculate the distance between the disaster-bearing body and the slope The distance and functional relationship of the disaster-affected body are obtained, and the horizontal load is compared with the ultimate load to obtain the vulnerability probability. The invention can accurately evaluate the vulnerability of the disaster-bearing body and provide a powerful basis for emergency treatment of landslide disasters.

Description

technical field [0001] The invention relates to the technical field of landslide monitoring, in particular to a device for assessing the vulnerability of landslide hazard-bearing bodies. Background technique [0002] Landslides and debris flows are geological disasters or engineering geological disasters that often occur in mountainous areas, on both sides of roads, on both sides of river valleys, and road construction sites. They erupt suddenly, cause great damage, and are difficult to control and predict. If the prediction is not timely, it will cause huge casualties and material damage. loss. [0003] Therefore, landslide disaster risk assessment has always been the focus of research at home and abroad. The key point of landslide disaster risk assessment is the vulnerability of hazard-bearing bodies. However, the current lack of research on the vulnerability of landslide hazard-bearing bodies has led to the delay in the study of landslide disaster risk assessment, which...
