PTC桩复合地基动态施工监测

Dynamic Construction Monitoring of PTC Pile Composite Foundation

针对高速公路PTC桩复合地基工程量特别大,工期控制紧迫,施工质量要求高、可借鉴经验少的特点,为严格控制PTC桩的施工质量,保证软基处理效果,通过地质差异、施工工艺和影响因素等方面研究,设计一套动态施工监测方案。实践表明,静压桩复合地基动态施工监测设计合理、方案可行、实施高效,可为同类工程提供经验借鉴。

For the PTC pile composite foundation of highway is characterized by large amount of work,urgent construction period,high construction quality requirement and less experience,in order to strictly control the construction quality of PTC piles,ensure the soft foundation treatment effect,a dynamic construction monitoring program was designed through a study of geological differences,construction techniques and influencing factors.The practice shows that the dynamic construction monitoring program of static pressure pile composite foundation is reasonable in design,feasible in program and efficient in implementation,which can provide experience for similar projects.
