SLOPE COLLAPSE EARLY WARNING SYSTEM
To provide a slope collapse early warning system capable of precisely evaluating a risk of slope collapse while appropriately reflecting planar deformation in a slope to perform stable and reliable warning on the basis of the evaluation.SOLUTION: A slope collapse early warning system is installed on a slope S and includes a number of tiltmeters 13 for measuring a tilt angle representing deformation in the slope S, calculates a number of tilt angular speeds Vn that are changing speeds of the tilt angle measured by a number of tiltmeters 13 (Fig. 8), calculates an average value of the tilt angular speeds Vn as a risk parameter (an entire risk parameter Valarm T, a sectional risk parameter Valarm D) representing a risk of collapse of the slope S (formulas (1), (2)), and gives warning when the risk parameter reaches a prescribed warning reference value VREFA (steps 3, 6, 8, 10, 12, 4 of Fig. 7).SELECTED DRAWING: Figure 7
【課題】斜面の面的な変状を適切に反映させながら、斜面の崩壊の危険度を精度良く評価でき、その評価に基づいて、安定した信頼性の高い警報を実行できる斜面崩壊早期警報システムを提供する。【解決手段】本発明による斜面崩壊早期警報システムは、斜面Ｓに設置され、斜面Ｓの変状を表す傾斜角を計測する多数の傾斜計１３を備え、多数の傾斜計１３によってそれぞれ計測された傾斜角の変化速度である多数の傾斜角速度Ｖｎを算出し（図８）、傾斜角速度Ｖｎの平均値を、斜面Ｓの崩壊の危険度を表す危険度パラメータ（全体危険度パラメータＶalarm Ｔ、区分危険度パラメータＶalarm Ｄ）として算出し（式（１）（２））、危険度パラメータが所定の警報基準値ＶＲＥＦＡに達したときに、警報を実行する（図７のステップ３、６、８、１０、１２、４）。【選択図】図７
