滇西北地区海巴洛泥石流发育特征及危害性评价

Development Characteristics and Hazard Evaluation of Haibaluo Debris Flow in Northwest Yunnan

泥石流具有较大粘滞性,且含有大量的固体颗粒,其搬运堆积能力及冲击能量远大于一般水流,对山区穿越泥石流的道路交通线破坏性较大。以滇西北地区丽香铁路项目海巴洛泥石流为依托,结合工程特点,对泥石流沟发育特征进行了分析,对泥石流的危害性进行了评价,并提出防治措施。

For the debris flow has large viscosity and contains a large number of solid particles, its handling accumulation capacity and impact energy is far greater than the general flow, resulting in large destructiveness to the road traffic lines in mountainous areas passing through it. The development characteristics of the debris flow gully is analyzed and the hazard of the debris flow is evaluated based on Haibaluo debris flow of Lijiang- Shangri-La railway project in Northwest Yunnan and combining with the project characteristics and the prevention and control measures are put forward.
