摘　　要：依托某船舶产业园区道路路基处理实例,针对场地上部3.5~4.3m的新近填土,从技术特点、工程造价及施工周期等方面进行不同地基处理方案的比选,最终采用低能量强夯联合水泥土搅拌桩复合地基方案。最终检测结果表明:低能量强夯联合水泥土搅拌桩复合地基加固效果较好,可大幅度提高地基承载力,加固桩间土层,消除大部分工后沉降,满足设计要求。Based on an example of road subgrade treatment in a certain shipbuilding industry park,for the newly filled soil of 3.5-4.3m above the site,comparison and selection of different foundation treatment schemes were conducted from the aspects of technical characteristics,engineering cost,and construction period,and the final solution is to use low energy dynamic compaction combined with cement-soil mixing pile composite foundation.The final test results indicate that low energy dynamic compaction combined with cement-soil mixing pile composite foundation has good reinforcement effect.It can significantly improve the bearing capacity of the foundation,reinforce the soil layer between piles,eliminate most post construction settlement,and meet design requirements.
