摘　　要：在水库地区软弱地基地段修建高速公路路堤,需要采用有效的方法对软基进行处理,以防路堤出现沉降不均、承载力下降、路面开裂和塌陷等问题。结合广东某高速公路软基处理工程实例,总结分析了深层搅拌桩法处理高速公路浸水路堤地段软基的施工工艺,并从施工现场质量管理和施工质量控制要点等方面详细探讨了施工质量控制方法,可为今后类似浸水路堤软基处理施工提供有益借鉴。When highway embankments are constructed on the soft foundation section of the reservoir area,the soft foundation should be dealt with by effective methods,preventing the embankment from uneven settlement,reduced bearing capacity,road cracking and collapse.Combined with an example of a highway soft foundation treatment project in Guangdong,the construction technology of the deep mixing pile used to treat the soft foundation of the highway flooded embankment section was summarized and analyzed.Moreover,the construction quality control method was discussed in detail from the aspects of construction site quality management and construction quality control points.It can provide useful reference for the construction of soft foundation treatment of similar flooded embankments in the future.
