Title:
斜面安定性評価システム、及び斜面安定性評価方法
Document Type and Number:
Japanese Patent JP7094208
Kind Code:
B2
Abstract:
To provide a slope stability evaluation system and slope stability evaluation method that can evaluate slope stability quantitatively and continuously, and that can perform relative evaluation so as to be able to compare with the conditions of other slopes.SOLUTION: The present invention evaluates slope stability by observing observation points using a positioning satellite S, and includes positioning data storage means 101, displacement speed calculation means 102, basic score setting means 103, observation point positional coefficient setting means 104, individual score calculation means 105, slope score calculation means 106, and stability level evaluation means 107. The observation point positional coefficient setting means 104 sets an observation point positional coefficient (that is set depending on the placement position of observation points, and for which a higher value is set for a slope lower section compared with a slope upper section) for each observation point. The individual score calculation means 105 calculates an individual score obtained by multiplying a basic score by an observation point positional coefficient for each observation point.SELECTED DRAWING: Figure 1
