灌注桩钢筋笼长度对承载力的影响

The bearing capacity of pile length of reinforcing cage of influence

抗拔桩来承担基础承受的上拔力是工程界常见的做法。在一些较深的地下工程中,钻孔灌注桩能提供较高的抗拔力,钢筋混凝土桩身与土层可以很好地结合,使这种桩具有良好的抗拔性能。但在实际工程中,施工方为节约成本,未能按照图纸施工,减少钢筋笼的长度,给工程质量带来隐患。

The uplift pile for foundation under pulling force is a common practice of engineering. In some deep underground engineering, the bored piles can provide higher pull-out force, reinforced concrete pile and the soil is a good way to combine, make the uplift capacity of pile with good performance. But in actual project, the contractor to save costs, fail to execute the works in accordance with the drawings, to reduce the length of reinforcing cage, brings to the engineering quality hidden trouble.
