石油储罐地基基础新技术研究——CFG扩顶桩的技术研究

New technology study on foundation of oil tank

为了发挥高承载力桩在复合地基中承载力高的优势,通过CFG桩扩大桩顶端面积,研究高承载力桩在大型石油储罐地基加固处理中应用的适用性和桩土复合地基体沉降的规律,进而揭示高承载力桩应用于大型石油储罐地基加固处理可能存在的各种问题,试图通过理论分析得出一些结论,供探讨研究。

For taking advantage of capacity of high bearing capacity pile in composite foundation,top area of pile is expanded by CFG pile.Applicability of high bearing capacity pile in reinforcement of large scale oil tank foundation and regulation of pile-soil composite foundation settlement are investigated,which reveal problems in application of high bearing capacity pile for reinforcement of large scale oil tank foundation.Some conclusions are obtained.
