振动沉模大直径现浇薄壁管桩技术及其应用(Ⅱ):工程应用与试验

介绍了振动沉模现浇混凝土管桩(简称PCC桩)技术在南京大厂区高坡土市政道路软基加固中的应用。对该新型桩基开展了一系列现场试验和检测，以其结果验证了该桩型的适用性，桩基承载力和复合地基变形满足了设计要求；通过低应变测试分析可知，所检测桩桩身质量是完整的。研究结果表明：振动沉模现浇混凝土管桩技术是高等级公路软基加固中的高效、经济的新技术。

Field pour concrete thin wall cased pile technology and its application (Ⅱ): Application and in-situ test

A case study on the application of field pour concrete thin wall cased pile technology in a municipal road with high earth fill in Nanjing Dachang District is conducted. A series of field detection and in-situ test have been performed; the results show that the bearing capacity satisfies the design capacity and the use of this style pile is successful. The low strain test shows that the pile quality is good. So the field pour concrete cased pile with vibrated steel tube mould technology is an effective and economical technology for soil improvement.
