自平衡法平衡点位置对基桩承载力影响的试验研究

Experimental Study for Equilibrium Point Position Effect on the Bearing Capacity of Foundation Pile Based on Self-balance Method

文章以自平衡法原理为切入点,以某城市桥梁基桩自平衡法竖向抗压试验为例,综合现场试验场地的地质条件,分析桥梁灌注桩基桩自平衡测试技术中依据规范经验公式计算所得出的"平衡点位置"对成桩后基桩极限承载力结果所造成的影响,为同类工程提供技术参考。

With the self-balance method principle as a starting point,with the self-balanced method vertical compression test of bridge foundation pile in a city as the example,and combining the geological conditions of field test site,this article analyzed the effect caused by'equilibrium position'calculated and obtained in accordance with empirical formula in bridge pouring pile foundation-pile self-balanced testing technology on the ultimate foundation pile bearing capacity results after completing the piles,thereby providing the technical reference for similar projects.
