丹江口水库陶岔渠首是南水北调中线工程重要组成部分之一。引渠全长4440米,闸首渠底高程140米,最大开挖深度40米,渠肩弃土堆置厚度6～10米以上,渠深12～47米,渠底宽35～30米,边坡1:3～1:4.5,每升高5～6米设宽2.5米的护坡道。渠道于1969年初动工兴建,自1970年4月起,陆续出现了滑坡14处。其中较大的8处都沿着全新统(Q_4)粘土和上、中更新统(Q_3或Q~2_2)裂缝粘土的层间软弱带滑移的。另外6处,发生在上更新统(Q_3)裂缝粘土中,规模较小,大部已清除。
Danjiangkou Reservoir Tao Cha canal first is the South-to-North Water Diversion Project one of the important components. Drainage channel length of 4440 meters, the head of the gate bottom elevation of 140 meters, the maximum excavation depth of 40 meters, the canal shoulder spoil soil pile thickness of 6 to 10 meters, 12 to 47 meters deep canal bottom width of 35 to 30 meters, Slope 1: 3 ~ 1: 4.5, every 5 to 6 meters to set up 2.5 meters wide slope protection. The canal was started construction in early 1969. Since April 1970, there have been 14 landslides. The larger 8 of them all slip along the weak zone between the Holocene (Q_4) clay and the upper and middle Pleistocene (Q_3 or Q_2 2) fractured clays. The other six, occurred in the Upper Pleistocene (Q_3) fractured clay, are small in size and mostly cleared.
