摘　　要：北部引嫩总干渠乌北段位于嫩江左侧滩地上和嫩江一级阶地前缘,渠道蜿蜒曲折,形成右侧高填方,左侧深挖方渠道,左侧深挖高度最大10m左右。2011年9月底北引总干渠乌北段38km处左侧渠堤发生滑坡破坏,经分析,膨胀土是造成北引渠道滑坡的主要原因。为了能为滑坡处理措施提供安全保障,采取了先控掉膨胀土滑坡,然后用土工织物分层铺盖填筑碾压,按计算设计成加筋土,进行柔性支护。Wubei section,the total channel of northern Nen River diversion is located in flood plain at left Nen River and at the age of Grade 1 terrace of the Nen River,the channel is shaped in curve,forcing a high embankment on the right,the left channel is excavated deeply,and the maximum height is about 10 meters.At the end of September in 2011 , the left channel was destroyed by slipping at 38 km of Wubei section of the total channel Nen River diversion, through analysis, expansive soil is the main reasons causing landslip of the northern Nen River diversion.In order to provide safe guarantee for slip, removing the expansive soil earlier and filling with texture in different lay,design reinforced earth by calculation for flexible support.
