Summary: | PROBLEM TO BE SOLVED: To provide a sloped ground disaster prediction system capable of performing an accurate determination by paying attention to the water content in the ground.SOLUTION: A sloped ground disaster prediction system comprises: a water content sensor for measuring water content in a ground of the sloped ground; and an analysis part for analyzing an output signal of the water content sensor. The analysis part includes: means for calculating the water content in the ground where the water content sensor is embedded; means for calculating an effective saturation obtained by dividing a difference between the maximum value and the minimum value of the water content with the difference between the maximum value and the minimum value of the water content as normalization content by the normalization content; and means for determining as the timing for issuing a warning when the effective saturation is equal to or more than a threshold value.SELECTED DRAWING: Figure 1
【課題】土中水分量に着目することで、より的確な判定ができる傾斜地災害予知システムを提供する。【解決手段】傾斜地の土中の水分量を計測する水分量センサと、この水分量センサの出力信号を解析する解析部とを有する傾斜地災害予知システムであって、解析部が、水分量センサの出力信号から、水分量センサが埋設された土中の体積含水率を算出する手段と、体積含水率の最大値と最小値との差を正規化定数として算出された体積含水率の最小値との差を正規化定数で割ることで得られる有効飽和度を算出する手段と、有効飽和度が第1の閾値以上となった場合に警報を発令するタイミングと判定する手段とを有することとする。【選択図】図1 |
