The greatly reduced capacity of a single pile resulting from the negative friction leaves the end-bearingpile unsuitable in the backfilling soil.
实例分析表明,由于桩侧负摩阻力的影响,单桩承载力大为降低。产生负摩阻力的土层,不宜采用端承型桩基。

Longitudinal vibration of an integral pile in an uniform soil with endbearing boundary or elastic bottom boundary undergoing vertical harmonic load is theoretically investigated.
分别对均质土中完整端承桩和弹性支承桩在垂直谐和激振力作用下的纵向振动特性进行了研究。

The impedance function of the endbearingpile in stratified soil has been obtained by the method of transfer matrix according to the theory of continuous medium mechanics.
