Warning and evacuation support system using landslides occurrence limit line, setting method of evacuation reference line and vigilance reference line and its program and its occurrence limit line, the evacuation reference line and warning reference line

摘要

[Summary] [challenge] individual slope or nonlinear occurrence limit line of landslides for individual mountain stream, well and easily configurable way precision evacuation reference line and vigilance reference line and the program and the individual slope to run it or non-linear generation limit line of landslides for individual streams, and it is an object thereof to provide a warning and evacuation support system using the reference line and the evacuation warning reference line. The invention relates to a process for calculating the potential risk of landslide disasters, a step of classifying the slope or mountain stream into groups, a step of calculating the average value of the potential risk of the plurality of groups, the classification that was for the discrimination boundary surface representing the occurrence risk of landslides for each group of each slope or landslides individual streams with a like process of calculating the weight of the connection of the intermediate layer and the output layer by using a neural network nonlinear occurrence limit line, to set the evacuation reference line and warning reference line.
