芜宣高速公路软基试验路水泥土室内配合比试验研究

The cemented soil interior ingredient ratio test research in the soft soil subgrade testing road of Wuhu-Xuangcheng Expressway

合肥至杭州公路芜湖～宣城段高速公路位于长江下游冲洪积河漫滩地区， Ｋ２＋ ５００～Ｋ２５＋ ５００分布有厚度不等的软弱土层，其厚度最大达 ３０ｍ，沿线桥头高路 堤和一般构造物的地基采用水泥土搅拌法进行处理。本文结合芜宣高速公路软 基试验路工程实践，旨在对用于加固饱和软土地基的水泥土搅拌法，进行水泥土

Wuhu - Xuancheng Expressway of Hefei - Hangzhou highway is located at the alluvial flood land of Changjiang lower reaches, The soft soil layer with different thickness is distributed between K2 + 500 and K25 + 500 with the thickness of 30 meter to the maximum. The subgrade of the high embankment on the either end of the bridge and that of the general structure along the road are treated in the cemented soil stirring method. Combined with the engineering practice in the soft soil subgrade testing road of Wuhu-Xuangcheng Expressway, this article's purpose is to conduct the cemented soil interior in-gredient ratio testing research on the cemented soil stirring method that is to reinforce the saturated soft soil subgrade.
