中文摘要: 摘要:汶川5·12地震不仅造成了特大地震灾害,同时还诱发了大量的次生山地灾害。大量崩塌、滑坡直接为泥石流活动提供了丰富的松散固体物质,并且地震造成大量坡体失稳和岩体破坏,使这些泥石流沟在今后较长一段时间内处于活跃期。2008年6月18日,位于重震区的茂县东兴乡竹包头沟暴发泥石流,将主河湔江堵断随后溃决,对临近的302省道造成了较为严重的危害。本文分析该沟泥石流发育的背景条件,并估计了该次泥石流的容重,计算了其流速和流量。通过对泥石流运动和成灾特征的分析,提出了应对措施,为相关研究和灾区恢复重建提供参考和依据。
Abstract:The Wenchuan Earthquake on May 12th not only caused huge earthquake disaster, but also placed a premium on secondary mountain harm. Plenty of landslips and landslides provided a lot of incompact solid matters for debris flow. The earthquake caused instability of slope and breakage of rock, and the debris flow ravines will be active in a long period. A debris flow happened in Baotougou in Maoxian on June 18th, 2008, it blocked Jiangjiang, caused debacle and destroyed the close provincial highway 302. This paper analyzed the background conditions of debris flow development, estimated the density, calculate the velocity and flow. It proposed the control measures and provided reference and basis for the relevant research and reconstruction by analyzing the characteristics of movement and causes of the debris flow.
