贵州省水口(黔桂界)至贵阳高速公路位于黔南、黔东南山岭区,地形、地质条件复杂,山高坡陡、沟谷深切,高山峡谷相对高差达数十米到数百米,地形起伏非常大,为更好地消化弃方,减少工程造价,部分路段设置了高填方路基。本文介绍了K252+723.517～+936.620段中心填高达42.5m的高填方路基工程,从设计、原地表处理、填筑工艺等方面,介绍了高填路基的设计、施工、变形控制等方面的成功经验。
Guizhou Shuikou (Guizhou-Guizhou border) to Guiyang Expressway is located in Qiannan, Qiandongnan mountains, topography, complex geological conditions, steep mountain slopes, valleys deep, alpine valleys relative elevation of tens to hundreds of meters, undulating topography Very large, in order to better digest abandoned square, reduce project cost, some sections set up high embankment. This paper introduces the high embankment filled with height of 42.5m in section K252 + 723.517 ~ + 936.620, introduces the design, construction and deformation control of high embankment from aspects of design, original surface treatment and filling technology success experience.
