桩基质量缺陷处理技术研究与应用

Research and Application of the Quality Defect Treatment of Pile Foundation

针对某体育馆工程桩基不能满足抗拔设计要求的实际情况,通过对钻孔灌注抗拔桩受力进行分析,综合考虑桩基技术要求、应用效果与经济效益,确定出在灌注桩上钻孔,穿入抗拔锚杆并锚入基底岩石,来达到增加抗拔能力的处理方法。

Based on the situation in one gymnasium project that the pile foundation cannot meet the uplift pile's designing requirements,through the mechanics analysis to the bored tension pile,considering the pile foundation's technical requirements,the effect of utilization and economic benefit,the authors make a reasonable treatment choice to raise the pullout resistance by the method of drilling holes in the bored concrete piles,penetrating the anti-weighs anchors and anchor them into the rocks in the bottom of the pile foundation.
