Rainfall thresholds for geological disaster early warning of Guizhou power grid

Rainfall is an important triggering factor of geological disasters. The Guizhou power grid is heavily threatened by geological disasters induced by rainfall. Therefore, establishing early warning indicators for geological disasters induced by rainfall in the Guizhou power grid is crucial for controlling geological disaster risks. This article analyzes the geological environmental conditions in Guizhou Province and summarizes the laws of geological disasters induced by rainfall in the power grid of Guizhou Province. The systematically collected geological disaster events from 2010 to 2020 were studied, the rainfall indicators that triggered these geological disaster events, and established discrimination indicators for rainfall induced geological disasters using the effective rainfall method. The discrimination indicators for the level of rainfall induced geological hazards in the short term (next 24 hours) and medium to long term (next 7 and 15 days) are provided, providing a basis for the risk prevention and control of geological hazards in the Guizhou power grid.
