摘　　要：为便于理解和应用《广东省公路路堤软基处理技术标准》,介绍了相对《广东省公路软土地基设计与施工技术规定》(GDJTG/TE01-2011)、《公路软土地基路堤设计与施工技术细则》(JTG/TD31-02)增加或修改的内容,对真空联合堆载预压卸真空后的软土抗剪强度、基于抗压强度的搅拌桩复合地基承载力、复合地基固结度计算、考虑桩间土绕流的刚性桩复合地基稳定分析、考虑桩土差异沉降的复合地基沉降计算、既有路堤换填轻质土厚度计算等的主要技术要点进行了解释说明。Main revision of Technical Code for Soft Soil Improvement of Highway Embankment in Guangdong Province has been introduced. Such technical contents have been explained as shear strength of soft clay after vacuum and filling preloading,bearing capacity of composite foundation confined by compression strength of deep mixing pile,calculation of consolidation degree of composite foundation,stability analysis of flow slide of embankment with rigid-pile composite foundation,calculation of settlement of composite foundation taking different settlement between pile and soil into account,calculation of replacement thickness of light soil of built embankment.
