“江口小学滑坡”在“5．12”地震期间发生变形，影响了学校综合楼的稳定性，给学校的正常教学秩序造成了安全隐患。文章通过野外调研和搜集现有资料，系统分析了该滑坡的地质环境和坡体特征。根据坡体的机构及形态特征研究了滑坡的形成机制，判定滑坡为牵引式土质滑坡，破坏模式为蠕滑拉裂。通过室内土工试验及反演分析合理确定滑带土的抗剪强度指标，并运用瑞典条分法、传递系数法进行滑坡各工况的稳定性验算，得出稳定性计算成果，最后通过各影响因子的敏感性分析，综合确定滑坡的稳定性，为后期工程治理提供设计依据。

The Landslide near by JiangKou primary school was deformed during the Wenchuan earthquake, which had an influence on stability and security of the School Building.This article systematic analysised the geological envi-ronment and slope’ s characteristicsby the way of feld research and collecting present data.This article studied of the for-mation mechanism of the landslide according to the slope of the morphological characteristics,and judged that the Jiangk-ou landside which was destroyed by the creep tension crack is a traction landslide.And reasonable assuranced the shear strength index of the sliding soil though the interior soil test and inversion analysis.And used the Swedish slice method and the transfer coefficient method to checking computations the stability of the landslide in various conditions,obtained calculation of the stable results.Finally,comprehensive identified landslide stability though the analysis of the various af-fecting factors and provided engineering design basis for the post-governance.
