摘要: Excess sediment yield during landslide events and annually has led to an increase in landslides, debris flows, and barrier lake disasters. Therefore, economic losses caused by sediment-related disasters damaging houses, schools, hospitals, roads, and other infrastructure have increased considerably. This study used Dazhong Village Landslide No.1 in Yilan County, Taiwan, as an example of a large-scale landslide area to develop risk assessment and adaptation strategies for 50-year and 200-year return period rainfall conditions. This information can be incorporated into local and national decision-making for emergency and evacuation planning in future landslide events.
大規模崩塌之重力土砂堆積,恐引發土石流或堰塞湖等複合型災害,倘若影響範圍內有重要建物, 或惟一聯外道路或橋梁等交通設施,則可能造成重大災害事件或造成孤島。本文假設不同發生情境,對宜蘭 縣大忠村一號崩塌地進行風險等級評估,並提出能降低災害發生可能性、縮減影響範圍及增加疏散避難時間 之工程調適策略,且以長期監測成果提出注意、警戒及疏散等監測管理值。最後,重新評估疏散避難處所需 求性及提出建議地點。
