Characteristics analysis of regional geological hazards based on spatial distribution of potential hazards

Abstract

Abstract The regional disaster scenario can be described by the disaster consequence and its evolution trend: the state of the disaster bearing body directly reflects the disaster consequence, and the relationship between the disaster bearing bodies leads to the complex and diverse evolution trend of the disaster consequence. Therefore, taking the disaster bearing body and its association as the core, a network model reflecting the characteristics of the disaster affected area is constructed to describe the regional disaster scenario. Based on the spatial distribution of potential hazards, the characteristics analysis method of regional geological hazards is proposed. This paper analyzes the regional elements of scenario architecture from a systematic point of view. Based on the evolution attribute of disaster bearing bodies, the influence range model of disaster bearing bodies and the influence topological association between them are defined, and the generation method of association network model of regional disaster bearing bodies is proposed. Using this method to construct disaster scenarios reflecting the characteristics of the affected area in advance is conducive to the assessment of the risk of regional disaster loss in advance.
