Unified Expression and Standardized Treatment of Railway Supergene Geological Disaster Risk Information

Abstract

Aiming at the problem that railway supergene geological disaster risk data are scattered and heterogeneous, and it is difficult to unify and centralize management and fusion analysis, the multi-source and heterogeneous supergene geological disaster risk data are standardized and integrated, and based on ontology theoretical knowledge, the digital model of main risk factors such as geography, geology, facilities and meteorology and their relationship is constructed to realize the unified expression of geological disaster riskinformation; Then, a standardized processing method of geological disaster risk data is proposed to realize three-dimensional modeling of geography and geology of railway facilities, and accurately extract multi-factor semantic features of disasters such as location and scope, and gather multi-source dynamic monitoring data such as displacement and meteorology, which provides key data support for scene analysis and visual expression of railway supergene geological disasters. Finally, landslide geological disasters around typical railway lines are selected for experimental verification and analysis, which proves that this method is reasonable and effective.
