Abstract

  A new evaluation method of a risk of slope failure during rainfall is proposed in this paper. In the new evaluation method, Principal component analysis (PCA) is employed, and the field measurement data (rainfall, pore-water pressure, ground displacement) are used as input parameter. Then, the effectiveness of proposing “principal component score (PCS)” as an evaluation index is investigated. As a result, PCS can be directly reflected rainfall intensity, water behavior in soil and ground displacement; and therefore it can be configured more concrete timing of dictating to evacuate and to release. Moreover, the soil tank test was also conducted, it was shown that the proposed method was the effective evaluation one.
