后压浆泥浆护壁灌注桩技术应用研究

Study on Application of Follow up Grouting Technology in Slurry Filling Pile

阐述了后压浆灌注桩技术、施工工艺及措施，对模型试验桩的静载试验表明，应用该技术可大大提高灌注桩的承载力并使其变形特性得到明显改善．该技术可供其他工程参考．

This paper presents the principle,construction process and technical treatment of the follow up grouting technology in slurry filling pile.The static loading test on model pile shows that the bearing capacity of filling pile is increased greatly and its deformation character is improved greatly by using this technology.It may be referential for other engineerings.
