摘要:
2020年6月17日,四川省甘孜州丹巴县半扇门乡梅龙沟暴发大规模泥石流灾害,形成暴雨-泥石流-滑坡-堰塞湖-洪涝灾害链。在前期短历时强降雨激发下,梅龙沟沟道径流沿途铲刮沟道松散堆积物,泥石流冲出量约2.4×105 m3,进入主河约1.3×105 m3,形成堰塞坝; 自然溃流后的泥石流坝残体挤压小金川河,迫使河水冲刷掏蚀对岸阿娘寨古滑坡坡脚,引发红梁木包包和烂水湾两处次级滑坡。古滑坡因之局部失稳复活,约6.6×106 m3坡体变形剧烈,坡体整体下挫,表面拉裂缝发育,强变形区边缘裂隙已经贯通,整体处于不稳定状态。分析表明,丹巴县梅龙沟灾害具有典型的灾害链生效应,严重危及上下游。现场监测表明,阿娘寨古滑坡整体滑动可能性大,如失稳后可能形成大规模堰塞湖,危险性极高,应提前防护应对。
Abstract:
On June 17, 2020, a rainstorm-triggering geohazard chain occurred near the Meilong catchment of Banshanmen town, Danba county, Sichuan province, China, which cascaded down consecutively in an order of debris flow, landslide, dammed lake and outburst flood. Upstream channel flow which produced by rainstorm of three hours strongly eroded sediment and loose material on the channel banks of the Meilong valley and transformed into sub-viscous debris flow. Total discharging volume in this debris flow event is up to 2.4×105 m3, and ca. 1.3×105 m3 of sediment rushed into the Xiaojinchuan river and blocked it temporarily. As a consequent of the river channel narrowing, the river flood scoured the foot of ancient landslide deposit of Aniangzhai on the opposite bank. The scouring induced two new landslides, the Hongliangmubaobao landslide and the Lanshuiwan landslides at the toe of the ancient landslide site. The two landslides eventually led to the revival of the Aniangzhai landslide. About 6.6×106 m3 of the ancient landslide deposits deformed strongly and fell integrally. Surface cracks developed on the severe deformation area have penetrated, and the ancient landslide is in an unstable state. The 6.17 Meilong disasters is a typical multi-hazard chain, which seriously and extensively endangered the upstream and downstream areas. On-site monitoring indicated that the overall sliding possibility of the ancient landslide is high, and a large-scale dammed lake may be formed if the Aniangzhai landslide fails. The risk of the ancient landslide's failure is extremely high, and effective countermeasures should be prepared in advance.
