通过工程实例分析了三岔双向挤扩灌注桩(简称DX桩)的施工工艺和技术要求;经静荷载试验验证了基桩的竖向抗压承载力、抗水平力及抗拔力都大大提高;结合提出的施工过程中相应的质量控制措施. DX桩能够使建筑结构更加稳定,沉降变形小,有节约材料,降低工程成本的良好效果.

Based on some engineering examples, the author analyses some key construction technologies and technical requirements of DX piles, proving that increasing the vertical compression strength improves the anti-horizontal force and uplift resistance of the base pile. Also proven is that, using this technique, the building structure is more stabilized with settlement and deformation reduced.
