楔形桩承载力试验研究

Experimental Study on the Bearing Capacity of Wedge Pile

为探讨楔形桩在天津地区应用的可行性 ,研究了楔形桩在竖向桩顶加荷方式下的极限承载力、桩侧摩阻力及桩端阻力的发展规律 ,并与同条件下等截面桩进行对比 ,分析其经济效果 ,证明楔形桩在天津地区具有一定的适用性 .

In order to probe into the feasibility of using wedge piles in Tianjin area,this paper studies the law of the variation of ultimate vertical bearing capacity,shaft resistance and tip resistance of a wedge pile by compressive loading on the top.Comparing with a pile of equal section under the same condition, we analyze its economic benefit and confirm that the wedge pile could be applied in this area.
