桩侧桩底注浆超长桩承载性能实验研究

On the experimental research on the bearing capacity of the super-long pile's grouting technique of pile side and bottom

提出了可以显著提高桩承载力的桩侧桩底注浆技术,研究了桩侧桩底注浆提高承载力的机理,对桩的承载性能进行了试验研究,对其静载试验结果作了分析,得出了桩的竖向承载力特征值。

The paper points out the grouting technique of pile side and bottom which can improve the pile＇ s bearing capacity obviously, researches the improvement mechanism of the bearing capacity of the grouting technique of pile＇s side and bottom, has a experimental test on the pile＇s bearing capacity, and analyzes the test results with the conclusion of the eigenvalue the vertical bearing capacity of the pile.
