Embodiment Construction

[0041] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments and drawings.

[0042] The GeoRVS (Geospatial Information-based Rapid Visual Screening, geographic information-based rapid visual screening) method constructed by the present invention requires a comprehensive and complex calculation process to generate damage index (DI) and building scores. The present invention utilizes and improves the recommendation algorithm combined with geospatial information technology, and then combines seismic and structural engineering technology and parameters to implement the Federal Emergency Management Agency (FEMA) method and DBJ51 / T068 (2016 and 2017) . After that, the present invention constructs a cloud-based platform for determining the vulnerability and risk assessment of buildings.

[0043] The present invention integrates major disciplines...

Abstract

The invention discloses a building damage risk screening method and system based on geographic space information integrated with geographic space information.. Therefore, the requirements of rapid visual screening of earthquake risks of large-range buildings can be met. The influence of multiple factors such as earthquake data, building internal and external structures and materials on earthquakebuilding damage is comprehensively and systematically studied; a universal building damage index calculation method and a decision support system based on machine learning are established; the low automation degree of building risk screening is broken through. The invention solves the problems of low reliability and the like in the prior art, realizes the functions of quick screening of vulnerability of buildings, risk assessment, automatic generation of reinforcement and reconstruction schemes and the like, can provide suggestions for prevention and emergency work before and after earthquakes, and provides decision-making suggestions for disaster prevention and reduction departments and related institutions so as to enhance the building structure.

Description

Technical field [0001] The invention relates to earthquake disaster assessment technology, in particular to a method and system for screening building damage risk based on geospatial information. Background technique [0002] Building damage risk screening is very important for the targeted reinforcement of buildings before and after the earthquake. It can achieve the purpose of reducing casualties and property losses, guiding post-disaster reconstruction and reducing reconstruction costs. Existing building damage risk screening methods are limited to local building codes and do not integrate geospatial information, such as low automation, poor reliability, inability to retrieve by geographic location and automatic intelligent assessment of loopholes and risks, low efficiency, Problems such as high cost, time-consuming, lack of scalability and customizability, etc., are difficult to be used for screening of various buildings at the regional level or even on a global scale. Drawin...
