摘要
通过４０余项工程实践及振冲碎石桩设计理论的应用，认为在工程设计中桩土应力比（ｎ值）必须进行实测，即ｎ＝ｆｐ／ｆｓ才能使得计算结果与实际相吻合。在以振冲密实为主的振冲碎石桩工程设计中，以置换率ｍ作为主要参数计算桩距的方法，可供处理地基时参考。
On the basis of more 40 engineering projects evaluation and of the the application of the design theory of the vibro-percussive detrital pile, it is proposed that n value—the stress ratio between pile and soil in the process of engineering design must be measured, namely, n=f p /f s , the calculation result can be in concordance with practices In the engineering design of the vibro-percussive detrital pile with mainly vibro-percussive densification, a calculation method of the pile distance as the main parameter by using the replacement ratio can be referred to the processing of foundation
