中文摘要黑竹沟滑坡群由3个滑坡组成,由南向北分为Ⅰ号、Ⅱ号、Ⅲ号滑坡,体积分别为2×10^4m^3、60×10^4m^3和10×10^4m^3。通过野外调查,详细研究了黑竹沟滑坡的地质环境和滑坡特征,分析了滑坡的形成机制及触发和破坏模式,得出结论为:Ⅰ号和Ⅲ号滑坡具有特殊地形条件,主要触发因素为河流冲蚀坡脚形成有效临空面以及公路开挖,导致坡体失稳;Ⅱ号古滑坡是其特殊的汇水地形造成大量地表水汇集,地表水是主要的触发因素。并以此为基础对滑坡群进行了稳定性分析和发展趋势预测。
英文摘要The landslide-group in Heizhugou is made up of 3 landslides, and is labeled Ⅰ , Ⅱ, and Ⅲ from south to north. The volume of landslides is 2 × 10^4 m^3 ,60 × 10^4 m^3 and 10 × 10^4 m^3. This article investigates the geological condition and characteristics of the landslide-group, and analyzes genetic factors, stability, and demolish pattern. The conclusion is that the major trigger of landslide Ⅰ and Ⅲ areerosion of rivulet, which of ancient landslide Ⅱ is the influx water of catchment valley; with this understands, the stability analysis and development trend is concluded. According to analyze the results of stability calculation model, ancient landslide lI is temporary stable unless extreme environmental transformation take place, and landslide Ⅰ and Ⅱ which stability coefficients are less than 1 are still unstable and very possibleto slide again and are suggested to construct engineering protection immediately.
