沟谷型滑坡⁃堰塞湖⁃溃决洪水灾害链的影响是工程地质领域一直关注的热点,而其运动过程则主要体现在滑坡堵江形成的堰塞坝地貌形态上。通过野外调查、无人机航拍和模型分析深入探讨了四川省巴塘县措纳学错堰塞坝的形成过程和灾害链运动特征。研究结果表明,研究区空间分布的复杂微地貌反映了滑坡体不同的运动特征,2#滑坡运动区与堆积区交界处滑坡物质由于左旋或右旋剪切运动形成滑坡垄;在堆积区2#III⁃1由于拉伸运动形成了滑坡台地;同时,在2#III⁃1边缘由于压缩运动形成了滑坡脊;在与1#滑坡接触碰撞下,滑坡物质发生翻转并倾覆至坝体中央,形成巨型块石组成的甲壳相;在堆积区末端2#III⁃3子区,滑坡体的径向扩展运动形成滑坡丘。同时通过现场调查分析了堰塞湖回水淹没过程,结果表明,回水淹没77.2 d后堰塞湖面由海拔3 298 m上涨到4 410 m,此时堰塞坝发生溃决。最后,计算了堰塞湖溃决洪水运动参数并对下游演进过程进行了分析,计算得到峰值流量约为27 392 m

The impact of the disaster chain of valley-type landslides, dammed lakes, and outburst floods has been a hot spot in the field of engineering geology, and its dynamic process is mainly reflected in the topography of the landslide dams formed by the landslides blocking the rivers. Through field surveys, unmanned aerial vehicles, and model analyses, the formation process and dynamic characteristics of the disaster chain of Cuonaxuecuo dam in Batang County, Sichuan Province, are discussed in detail. The research results show that the spatially distributed complex micro-topography of the study area reflects the different dynamic characteristics of the landslide body. The 2# landslide material at the junction of the landslide translation area and the accumulation area forms landslide ridges due to continuous sinistral or dextral shearing motions. Landslide platforms were formed in the accumulation area 2#III-1 due to a rapid extensional sliding process. Meanwhile, landslide ridges were formed on the edge of 2#III-1 due to compression-dominated processes. Under the contact and collision with 1# landslide, the landslide material overturned to the center of the dam, forming carapace facies composed of giant rocks. In sub-zone 2#III-3 at the end of the accumulation zone, the rapid radial spreading motion of the landslide body formed hummocks. At the same time, the backwater inundation process of the dammed lake was analyzed through on-site investigation. The results show that the surface of the dammed lake rose from 3 298 m to 4 410 m after 77.2 days of backwater inundation, and the dammed lake outburst. Finally, the outburst flood movement parameters are calculated and the downstream evolution process is analyzed. The calculated peak flow is about 27 392 m
