峨眉山地区滑坡分布及唐河坝滑坡稳定性评价(附答辩文稿)

摘 要 此次峨眉山地区的滑坡调查，主要任务是在查清峨眉山地区滑坡的分布特征的基础上，对代表性的滑坡进行稳定性评价，并对滑坡的防治提出初步的建议。 首先根据滑坡形成的机理，划分出有待研究的地区，进行了一系列的实地调查。查明了峨眉山地区滑坡分布的特征，滑坡主要分布在软硬岩层互层的，坡度小于45°的同向斜坡。并对滑坡个体的特征进行勘察，归纳出这个地区滑坡的形成、分布的共性。然后，选择了代表性的滑坡（唐河坝滑坡）进行了稳定性评价，得出该滑坡目前处于稳定状态。讨论了影响斜坡稳定性的因素，最后提出了针对峨眉山地区滑坡应该采取的防治办法。 [关键词]： 斜坡 滑坡 分布特征 稳定性评价 The Distribute Character of Landslide in Emei Mountain Area and Stability Evaluation of Tangheba Landslide Abstract The main task of this investigation of the landslide in Emei mountain area is to make a stability evaluation to some representative landslide , present some elementary conclusions and recommendations to prevent the landslide. First we divided some research areas according to the formation mechanics of Landslide, have a series of field research. Established the distribution character of the landslide in Emei mountain areas. Have a reconnaissance to the distinction of individual landslide. Induct the general character of landslide’s formation and. Then choose a representative landslide(Tangheba) to make stability evaluation. Discuss the factor which impact the sloping ground’s stability. At last ,this paper present some recommendations to prevent the landslide against Emei mountain areas. Keywords: landslide sloping ground stability evaluation distribution character
