Mechanism of the “7·15” debris flow in Baiguoshu gully, Tianquan County, Sichuan Province

  • 摘要: 相较于宽缓沟道型泥石流,小流域窄陡沟道型泥石流具有更高的隐蔽性和突发性,揭示此类灾害成灾机理无疑对工程治理及灾害预防具有重要意义。本文以发生在四川省天全县白果树沟2021年“7·15”突发性泥石流为例,借助野外调查、无人机航测与RAMMS流体动力学模拟,揭示了此次泥石流的成灾过程。结果表明:白果树沟泥石流是累计前期降雨和短时强降雨共同作用的结果,其起动源于上游饱水物源被山洪揭底,而沿途侧蚀冲刷沟岸形成的滑坡为泥石流提供了物源补给,沟内局部堵溃后又进一步放大流量、导致沟口成灾,淤埋雅康高速公路路面。从发展趋势看,白果树沟现阶段物源丰富,水动力条件良好,仍存在暴发泥石流的可能性。
