关于桩端注浆提高桩基承载力试验效果的研究

Study on the grouting of pile tip improving bearing capacity of pile foundation testing effect

介绍了钻孔灌注桩桩端后注浆法的加固机理、施工过程及方法,探讨了桩端注浆法在具体工程中的应用效果,指出桩端后注浆法提高了桩基承载力,减小了基础沉降,值得推广使用。

The strengthening mechanism, construction progress and method of bored pile tip post-injecting method were introduced, the application effect of grouting method of pile tip in practice engineering was discussed, and it pointed out that pile tip post-injecting method irnproved bearing capacity of pile foundation, reduced foundation settlement, and was worth to popularize and apply.
