Method for evaluating damage loss rate of buildings under action of landslide instability movement

Abstract

The invention provides a method for evaluating the damage loss rate of buildings under the action of landslide instability movement. The method comprehensively considers the action force of the landslide movement on the buildings after landslide instability occurs and the resistivity of the buildings under the action of landslide bodies, a spring deformation block analysis model of a landslide is built to analyze the movement process after landslide instability occurs, then the action force of the landslide on the buildings is determined and serves as the impact resistivity value of the buildings, then through calculation of interlamination yield shearing force of the impacted building framework structures, the impact resistivity value of the impacted buildings is determined, the specific value of the landslide hazard strength value and the impact resistivity value of the buildings serves as the damage loss rate value of the buildings, and the damage loss rate of the buildings under the action of landslide instability movement is determined; the whole analysis process is objective and reliable, can contribute to improvement of accuracy of landslide instability hazard evaluation, and the problem that the big error exists in landslide instability hazard evaluation conducted according to human experience is solved.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and disaster reduction evaluation, in particular to a method for evaluating the degree of damage and loss of buildings under the action of landslide instability. Background technique [0002] In recent years, research on landslide disaster risk has become a hot spot in the field of landslide research. Some mainstream countries in the world have carried out relatively in-depth research work. Scholars at home and abroad have gradually developed from the understanding of the basic concept of landslide disaster risk to quantitative prediction. Degree. In risk research, the evaluation of the degree of damage loss of the impacted body is the core of this research, and the quantitative determination of the degree of damage loss of the impacted body has always been a difficult point in this field. [0003] At present, the evaluation of the degree of damage and loss of impacted bodies is mostl...
