Other Abstract

2016年5月8日福建泰宁县开善乡金溪左岸的芦庵坑沟发生了特大规模的灾害性泥石流,导致36人死亡失踪。现场调查表明,本次灾害为稀遇低频、粘性、特大规模、灾害型沟道泥石流。泥石流容重达2.0 g/cm~3。沟口扇顶上游120 m的流通区断面泥石流流速达到12.2m/s,泥石流流量830 m~3/s,泥石流运动时间2 min,一次固体物质总量为1.9万m~3,泥石流的颗粒冲击力达900 t。泥石流成因系沟床与坡面崩滑堆积物在高频率的雷声与强暴雨联合作用下引发。

On May 8th,2016,a catastrophic debris flow hit the Luankeng gully,located at the left bank of Jingxi river,in the vicinity of Kaishan Town,Taining County of Fujian province,causing 36 people dead or missing.Field investigation revealed that it was a large scale,rare,low frequency and viscous type debris flow.The debris flow density was up to 2.0 g/cm3 and its velocity arrived at 12.2 m/s obtained at the survey point in the travelling course of the debris flow,120 meters upstream away from the gully mouth. Discharge of debris flow reached to 830 m3 /s with a duration of 2 minutes,a total amount of solid matter 1.9 million m3. Its impact force reached to 900 tons.The initiation mechanism of the debris flow was speculated in that the gully bed deposits and slope collapse accumulations was motivated to form debris flow under the combination of high frequency thunder and heavy precipitation.
