GROUND SPECIFIC ELECTRICAL RESISTANCE MONITORING DEVICE, AND SLOPE COLLAPSE WARNING SYSTEM
To provide a ground specific electrical resistance monitoring device and slope collapse warning system that can easily acquire specific electrical resistance of a desired depth in ground with power saving and in a short time, can evaluate a risk level of slope collapse on the basis of an acquired result, and can implement a warning high in stable reliability.SOLUTION: A specific electrical resistance monitoring device comprises: a pair of current electrodes that is installed in ground; and a plurality of sets of potential electrodes that is disposed on an outer side of the pair of current electrodes. The specific electrical resistance monitoring device is configured to supply a prescribed current to the pair of current electrodes; measure a potential difference between two potential electrodes of each set; and calculate specific electrical resistance of a prescribed depth of the ground respectively on the basis of the prescribed current and measured potential difference. A slope collapse warning system is configured to: calculate a thickness ratio of aquifer in a soil layer as a risk level parameter representing a risk level of slope collapse on the basis of the specific electrical resistance of the ground obtained by the specific electrical resistance monitoring device; and implement a warning when the risk level parameter reaches a threshold.SELECTED DRAWING: Figure 1
【課題】省電力かつ短時間で、地盤における所望の深さの比抵抗を容易に取得することができ、その取得結果に基づき、斜面崩壊の危険度を評価し、安定した信頼性の高い警報を実行することができる地盤の比抵抗モニタリング装置及び斜面崩壊警報システムを提供する。【解決手段】比抵抗モニタリング装置は、地盤に設置された一対の電流電極と、それらの外側に配置された複数組の電位電極と、を備え、一対の電流電極に所定電流を通電して、各組の２つの電位電極間の電位差を測定し、所定電流及び測定された電位差に基づいて、地盤の所定深さの比抵抗をそれぞれ算出する。また、斜面崩壊警報システムは、比抵抗モニタリング装置によって得られた地盤の比抵抗に基づき、土層における帯水層の厚さの割合を、斜面崩壊の危険度を表す危険度パラメータとして算出し、危険度パラメータがしきい値に達したときに、警報を実行する。【選択図】図１
