摘　　要：以长沙市郭亮南路某路段杂填土地基处理方案为例,对复合地基碎石桩方案以及局部换填方案进行了地基承载力及沉降计算分析,并从技术指标、造价、工期等方面综合比选,确定了厚度较大的杂填土地基处理方案,可为同类型城市道路杂填土路段地基处理方案的决策提供参考。This paper takes the miscellaneous fill treatment plan of a section of Guoliang South Road in Changsha City as an example. The foundation bearing capacity and settlement check are carried out for the gravel pile scheme and the partial replacement scheme,and comprehensive selection and comparison of technical indicators,cost,construction period,etc,determined the treatment plan for the miscellaneous fill with large thickness. It can provide reference for the decision-making of ground treatment plan for the same type of urban road miscellaneous fill road section.
