摘要:
2012年7月14日,四川石棉田湾河流域唐家沟暴发泥石流,造成2人死亡、5人失踪及巨大经济损失。泥石流由沟道中上游局地强暴雨激发,形成机制为沟床起动型,持续过程约1 h,泥石流总量约85×104 m3,为低频率特大规模泥石流。唐家沟的相对高度为3 139 m,沟道陡急而多急弯、卡口,导致泥石流在运动中反复堵塞溃决,堵塞系数为2.5~3.0;在沟道中下游,泥石流获得了原有沟床堆积物的补给,使固体物质补给区范围扩大,规模增大,危害能力增强;流体含有2%~4.4%的黏粒,黏度较大,重度达20.6 kN·m-3,搬运力极强,搬运至沟口的最大石块体积约235 m3,质量约645 t;流体的直进性强,弯道超高高度高于11 m。泥石流堵塞田湾河并形成溃决灾害,构成了泥石流堰塞湖山洪组成的山地灾害链,危害由沟道延伸至主河两岸的较大范围。当地森林植被茂密,但泥石流十分发育,表明生态环境良好的山区仍需加强对泥石流灾害的防范。
