摘　　要：九道河倒虹吸位于云南省楚雄市禄丰县境内西河峡谷,谷峰相对高差280 m~360 m,河谷呈“V”形,是典型的深切峡谷。以九道河倒虹吸工程为背景,针对深切峡谷陡坡施工期间边坡安全稳定性分析,采用GeoStudio软件中的SLOPE/W模块建立边坡模型,主要分析边坡段倒虹吸镇墩采用不同的施作顺序对边坡安全稳定性的影响。根据不同施作顺序边坡安全稳定性的变化情况,寻找更为合理的施作顺序,分析结果对同类型工程的施工有着实际的指导意义。Jiudaohe inverted siphon is located in Xihe canyon,Lufeng County,Chuxiong City,Yunnan Province.The relative height difference between the valley and peak is 280 m ~ 360 m,and the valley is V-shaped,which is a typical deep canyon.Taking Jiudaohe inverted siphon project as the research object,to analyze the deep slope stability during the construction of deep canyon,SLOPE/W module in GeoStudio soft ware is adopted to establish the slope model.The influence of different construction sequences of the inverted siphon pier on slope stability is analyzed.According to the variation of slope stability in different construction sequence,a more reasonable construction sequence is found.The analyzed results are meaningful to the same projects.
