陶岔引汉渠首枢纽的引水渠全长4公,渠底高程140米,底宽30～35米,边坡1:3～1:4.5,每5～6米设戗台一级,最大挖深47米。渠道1969年开工,1974年建成。施工中陆续出现滑坡,竣工时仍然存在八处滑坡。为了防止滑坡影响输水,施工时曾采取了以支挡减载为主,排水为辅的整治措施。这些处理方法,直接经受十多年丹江口水库高低水位涨落变幅的考验,滑坡体基本 The drainage channel of Taocha lead Han canal hub is 4 kilometers in total length. The bottom elevation is 140 meters and the bottom width is 30-35 meters. The slope is 1: 3 ~ 1: 4.5 and every 5 ~ 6 meters. Dig deep 47 meters. Channel started in 1969, completed in 1974. Landslides continued to emerge during construction, with eight landslides still being completed. In order to prevent the landslide from affecting the water conveyance, the construction measures have taken the remediation measures such as supporting and deloading, supplemented by drainage. These treatment methods are directly tested by the fluctuating amplitude of the water level in the Danjiangkou Reservoir for more than ten years. The basic of the landslide body
