Abstract

The invention provides a rainfall capacity risk ranking method and apparatus used for geological disaster region assessment pre-warning. The method and the apparatus are used for the geological disaster region assessment pre-warning. The method comprises the following steps of dividing the whole nation into a plurality of points, and calculating accumulated rainfall capacity of each point in a preset time; determining a first rainfall capacity level and a first rainfall capacity ranking weight of each point falling into each province according to the accumulated rainfall capacity of each point in the preset time; dividing the whole nation into a plurality of geological environment regions; determining a second rainfall capacity level and a second rainfall capacity ranking weight of each point falling into each geological environment region according to the accumulated rainfall capacity of each point in the preset time; and coupling the first rainfall capacity ranking weight and the second rainfall capacity ranking weight corresponding to each point, and generating a rainfall capacity ranking graph. According to the method provided by the invention, the influences of rainfall capacity on different provinces and different geological environments are considered at the same time, so that the actual conditions are better met and the potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of geological disasters, in particular to a rainfall risk classification method and device for regional assessment and early warning of geological disasters. Background technique [0002] The transmission line covers a wide range and has a long transmission distance. Along the way, it passes through many areas with harsh environmental conditions, complex geological terrains, and variable climates, such as the Yangtze River Basin in my country and southwest mountainous areas. There is abundant rain all year round, and there are many types of geological disasters. Geological disasters such as landslides and subsidences occur frequently. At the same time, affected by human activities, various construction and mining activities around the transmission line have a great impact on the originally fragile geological environment, which can easily lead to the inclination, deformation and settlement of the transmission ...
