- Title:
- Study on Characteristics and Formation Mechanism of Geological Hazards in Kangding County of Sichuan Province
- Keywords:

- 摘要:
- 康定县地质灾害类型众多，主要有滑坡、泥石流、不稳定斜坡（崩塌危岩体及滑坡变形体）等。康定县境内现有地质灾害107处，其中滑坡41处、泥石流42处、不稳定斜坡（崩塌危岩体和滑坡变形体）24处。地质灾害规模以小型为主，占67.29%，其次为中型和大型，有少量巨型地质灾害。地质灾害主要分布于东部高山峡谷区和西部高原深谷区，东部高山峡谷区地质灾害主要沿大渡河两岸及其支流展布，西部高原深谷区地质灾害主要沿雅砻江及其支流展布。在资料收集与野外调查的基础上，从地形地貌条件、地层岩性条件、地质构造条件、降雨、人类工程活动、地震活动等方面探讨了地质灾害的形成机理，并提出了防灾、减灾对策。
- Abstract:
- Landslide, debris flow, unstable slope (rockfall and landslide plasmodium) are the main types of geological hazards in Kangding county. 41 landslides, 42 debris flows, 24 unstable slopes (rockfall and landslide plasmodium) have been found in Kangding county. 67.29% of geological hazards are minitype dimensions, next are medium-sized and large-scale, gigantic and a few geological hazards. Geological hazards mostly originate from alp gorge section of east and altiplano clough section of west. Geological hazards follow Dadu river and its branch in the alp gorge section of east, and follow Yagong river and its branch in the altiplano clough section of west. Through collecting data and surveying in the locale, the authors discuss the formation mechanism of geological hazards from condition of terrain and physiognomy, stratum and lithology, geological structure, rainfall, human activity, earthquake and so on, and bring forward countermeasure for prevention and reduction of geological hazard.
