摘要
分析了南京市浦口滨江大道项目建设的特点,比较了路堤结合和路堤分离两种设计方式以及自然土方和人工吹填沙两种填料的优缺点。根据项目建设情况和比较结果,推荐道路建设采用路堤结合的方式,填料采用吹填沙。结合其他相关项目的经验和试验段的试验结论,提出了适用于路堤结合段吹填沙的沙质要求、压实度要求等设计技术标准,以及吹填沙路基的施工步骤和注意事项。同时分析了施工完成后的检测结果,总结了此类项目的设计经验,可为其他同类工程的设计与施工提供参考。
The characteristics of the construction of the project at riverfront revenue in Pukou region of Nanjing City are ana- lyzed, and the advantages and disadvantages of two design modes （ road - embankment integrated and road - embankment separa- ted） and two fillers （natural earthwork and hydraulic fill sediment） are compared respectively. According to the construction sit- uation and comparison results, the road - embankment integrating mode is recommended and the hydraulic fill sediment is adopt- ed. Combining with the experiences of other projects and conclusion of the trial section, the technical standard such as demand of quality and compactness of hydraulic fill sediment are put forward, so are the construction steps and points for attention of sedi- ment embankment. The quality check results after construction are analyzed, the design experience is summarized.
