【摘要】 鲁滩坝滑坡位于竹溪县新州镇鲁滩坝村。自2016年以来,鲁滩坝滑坡一直处于持续变形阶段,直接导致其下方部分居民房屋被破坏。本文在掌握滑坡区地质资料的基础上,结合现场调查访问,对鲁滩坝村滑坡的地质与变形特征进行了详细的描述;并通过BP神经网络对滑坡进行敏感性分析得出结论,在降雨工况下该类滑坡可能发生局部圆弧形滑移破坏,发生整体或大规模滑移变形破坏的可能性较小。本研究对类似工程稳定性分析具有借鉴与指导意义。更多还原

【Abstract】 Lutanba landslide is located in Lutanba village, XinZhou town, ZhuXi county. Since 2016, the Lutanba landslide has been in a continuous deformation stage, directly causing the destruction of some residents’ houses below it. Based on the geological data of the landslide area and the field investigation, the geological and deformation characteristics of Lutanba landslide are described in detail.Through the sensitivity analysis of the landslide by BP neural network, the conclusion is drawn that under the working condition of rainfall,this kind of landslide may occur partial circular arc slip failure, and it is less likely to occur overall or large-scale slip deformation failure.This study has reference and guiding significance for the stability analysis of similar projects.更多还原
