摘要
分析了桩端后注浆提高桩基承载能力的工作原理,并利用后注浆技术成功处理了桩端存在软弱夹层中的工程实例,认为采用桩端后注浆技术能够较大幅度的提高单桩承载能力,但其提高程度还需要通过现场试验确定.
First of all,this paper analyses the working principle of increasing the bearing capacity of the piles in post-grouting and then presents an engineering example for successively treating the weak intercalated layers in the ends of piles by using the technique.In conclusion,it shows that the bearing of piles can be significantly increased by applying the post grouting technique in the ends of piles,but the increments need testing by field monitoring.
