Abstract
We presented the system that can forecast the collapse of cut-off slope using standard data based on neural network in the preceding paper. Data must be carefully selected for precision forecasting using neural network. In this system, the difference between the non-collapsed data and the collapsed data causes the uncertainty in results. Especially, the rainfall data is very important factors for this system. In this research, we present new rainfall factors called n-hours rainfall and attempt to provide more information for the system to obtain more assured results. We confirm that these factors is applicable to the system.
