초록

The objective of this study is to suggest rainfall threshold for landslide forecasting and warning. For this study, we chose the researcharea where landslide have occurred. And we performed infiltration-stability analysis with rainfall intensity-duration. As the results ofthis study, slope stability variation chart with rainfall intensity-duration are established. This kind of chart is believed to be able to beused for forecasting and warning the landslide caused by rainfall.
