摘要: 长江三峡地区滑坡众多,杉树槽滑坡属于典型的顺层基岩滑坡。通过对滑坡发生后追踪调查,介绍了滑坡的地理位置、周边地质概况及其基本地质特征,并将滑坡发生前后的地形地貌和地质特征进行对比,直观地表明了滑坡发生、发展及运动的过程。最后,探讨了湖北省杉树槽滑坡发生的影响因素及形成机理,并认为脆弱的地层结构和不利的地貌形态是滑坡发生的内因,而降雨是诱发滑坡的关键外在因素,其为典型的剧动推移式降雨型顺层岩质滑坡。

Abstract: There are plenty of landslides in Three Gorges reservoir area and Shashucao landslide is a typical bedding rock landslide. Through follow-up investigation after the landslide occurrence, the geographical location, the surrounding geology and basic geological characteristics of landslide were introduced. And the topography and geomorphy as well as geological characteristics before and after landslide were contrasted, which intuitively indicated the process of landslide occurrence, development and motion. Eventually, the influence factors and formation mechanism of Shashucao landslide in Hubei province were discussed. It is discovered that the vulnerable stratum structure and unfavorable geomorphologic shape are the internal causes of landslide occurrence, and rainfall is the key external factor to induce landslide. Shashucao landslide is a typical elapse precipitation type of bedding rock landslide.

Key words: geotechnical engineering, landslide, bedding rock, geological features, rainfall
