bottom bearing load

Longitudinal vibration of an integral pile in an uniform soil with end bearing 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 results show that the arch distortion weakens structural ultimate load bearing capacity, and increases lateral displacement at the bottom of .

分析表明，拱肋变形降低了结构的极限承载能力，并增大了其在正常使用状态下的侧向变形，以致拱脚外包混凝土开裂严重。
