초록
The main purpose of this work is to analyse damages caused by debris flows during the heavy rainfall at Inje province in Kangwondo, Korea. A series of site investigations have been performed to survey the characteristics of debris flows occurred during the summer season of 2006. It has been found that major losses and costs are triggered by discharge of soil and rock fragments from landslides. During the rainfall unexpectedly high precipitation rate of 113.5mm/hour and 355mm/day was recorded, which could happen at a 80-500 year period. Comparing the period of the rainfall with the time of the landslides, it has been found that the occurrence of the landslides is directly related to heavy rainfalls. At present, several debris barriers have been built at the valleys and natural slopes have been protected by the seed spray method. It is intended to propose an appropriate solutions of restoration of landslide damages and maintenance based on findings from the current study.
