阿尔塔什面板坝高边坡支护脚手架的设计及应用

Design and Application of High Slope Supporting Scaffold at Aertash CFRD Project

阿尔塔什水利枢纽工程是目前新疆在建的最大的水利工程,工程因其在设计和施工方面存在超高面板堆石坝、深河床覆盖层、工程区强地震带以及坝体右岸存在国内罕见的高边坡危岩体等技术难题,被业界称为“新疆三峡工程”。右岸高边坡支护工程施工区域坡高、陡、岩层地质条件复杂,在高约600m的边坡区域(岩面自然边坡约为75°~80°,局部接近90°、部分呈倒悬状)进行施工,脚手架的设计及应用在整个高边坡支护施工过程中就显得尤为重要。

Aertash Water Conservancy Project is the biggest water conservancy project under construction in Xinjiang Province. It is called by the industry as “The Three Gorges of Xinjiang” because a series of technological challenges in design and construction. The right bank high slop supporting construction area is high and steep with complex rock mass geological condition, the natural slope of slope area rock surface at height of about 600m is around 75°~80°and locally approaches 90°with some parts hanging, therefore, the scaffold design and application in slope construction is particularly important through the whole high slope supporting construction period.
