    Hazard Assessment of Debris Flow Triggered by Outburst of Jialong Glacial Lake in Nyalam County, Tibet

    • 摘要: 冰湖溃决型泥石流是高原山区特殊的地质灾害,以西藏聂拉木县嘉龙湖为例,建立了一套冰湖溃决型泥石流危险性评价方法.以喜马拉雅山区1970—2015年气温波动频次和聂拉木冰湖溃决历史事件预测了未来10年嘉龙湖溃决的时间概率.利用遥感影像识别嘉龙湖上方不稳定冰体的范围和规模,采用美国土木工程师协会推荐公式和修正的三峡库区涌浪计算方法分析了冰川滑坡产生的涌浪规模,从涌浪波压力和越顶水流推力两方面预测了冰碛坝发生失稳的可能性.采用FLO-2D模拟冰湖溃决泥石流的运动过程,以最大流速和泥深表达了嘉龙湖溃决泥石流的危险程度.评价结果表明:2002年嘉龙湖溃决事件与当年气温偏高有关,未来嘉龙湖发生溃决概率高;冰川滑坡激起涌浪能够翻越坝顶,并引起坝体快速侵蚀而溃决;冰湖溃决泥石流对聂拉木县城河道两侧54栋建筑造成威胁.评价方法实现了冰湖溃决型泥石流危险性的定量分析,评价结果对聂拉木县城泥石流防灾具有现实意义.
