摘要
】用Ｖｅｓｉｃ球孔扩张理论对钻孔桩桩底灌浆的压密机理进行了分析，给出了计算桩端承载力的公式，同实测值进行了比较，给出了一种理论计算方法及设计原则。
On the basis of Vesic ball hole extension theory,the tamping mechanism of bored piling bottom grouting is analyzed.The pile end bearing capacity formula is proposed and compared with field measuring data.A theoretical calculation method and design principle are put forward.
