Abstract
There are many studies on setting a critical line for prediction of slope failure caused by rainfall. The focus of these studies lies in the determination of the boundary between dangerous region and safety region with single criteria. However, because of the complexity of nature, it is almost impossible to distinguish complicated slope failure with them. In this study, we use rain data both on failure rain and un-failure rain and made up the data with two dimensions: short term estimation as hourly rainfall and long term estimation as effective rainfall. We compare the results with conventional Critical Line and showed the effectiveness of the proposed method.
