摘　　要：在平推式滑坡的稳定性分析中,暴雨是诱发滑坡失稳的重要因素。利用平滑式滑坡的力学模型,采用天然工况和暴雨工况对三台县中新中学滑坡进行了稳定性计算,结果表明暴雨产生的后缘裂隙静水压力是中新中学滑坡可能失稳的最主要因素。Rainstorm is an important induced factor of unstability of a landslide. This paper uses the mechanical model for horizontal sliding landslide for calculating stability of the Zhongxin Middle School Landslide in Santai County, Sichuan. The results indicate that hydrostatic pressure in fissures resulting from rainstorm may be responsible for unstability of the landslide.
