摘要
本文针对广州市轨道交通十四号线一期(施工6标)土建工程桥梁桩基有部分处于岩溶地区,复杂多变的隐伏岩溶形态给桥梁桩基施工带来较大的困难。项目部通过技术研究,优化施工方案,对岩溶强发育区桩基施工工艺进行完善和改进,为项目部桩基施工按节点工期完成保驾护航,对今后同类型桩基施工中提供经验参考具有十分重要的意义。
In this paper,the pile foundation of the bridge in the civil engineering of Guangzhou metro line 14 phase I(construction bid 6)is partially located in the karst area,and the complex and changeable hidden karst forms bring great difficulties to the construction of bridge pile foundation.Through technical research,the project department optimized the construction scheme,improved the pile foundation construction technology in Karst strong development area to guarantee the completion of pile foundation construction of the project within the node construction period.It is of great significance to provide a reference for the same type of pile foundation construction in the future.
