摘　　要：芭蕉树滑坡位于云南省哀牢山东麓,发生于2002年8月14日。本文详细介绍了芭蕉树滑坡的基本工程地质特征,并由此概化出滑坡形成的地质力学模型;应用极限平衡法对天然状态及暴雨状态下斜坡的稳定性进行了分析研究。分析结果表明芭蕉树斜坡在不考虑暴雨作用下处于稳定状态,而在暴雨触发作用下将失稳滑动。The Bajiaoshu landslide occurred at the north foot of the Ailao 2004. This paper gave a detailed description of the basic engineering Mt., Yunnan Province on 14th August, geological features of the landslide, summarized a geomechanics model of the landslide to form, and made an analysis of the stability of slope in natural state and rainstorm using limit equilibrium method. The results indicated that the Bajiaoshu slope could maintain stability in natural state and would be instable and slide under the action of rainstorm.
