砂砾桩处理沼泽段软土地基技术应用

Application of Gravel Pile in Treatment of Soft Foundation in Swamp Area

结合S321线火烧桥至额尔宾山项目,对砂砾桩施工过程及控制要点进行分析总结,得出采用砂砾桩挤密加固技术可确保公路路基顺利通过沼泽段和淤泥段的结论,同时合理的施工技术可以有效缩短工期,提高公路投资效益,为公路施工提供更多选择方案。

Combined with the project of Xinjiang S321 provincial highway from Flaming Bridge to Erben Mountain, the construction process and crucial control points of gravel piles were summarized, and it was found out that enhancing with dense gravel piles can make sure the subgrade in swamp area will meet the technical requirements, and it also shortens the construction period and brings more benefit to highway investment, making it another plan for highway construction.
