摘    要:挤扩支盘桩是从普通混凝土灌注桩衍生出来的一种新桩型。与普通混凝土灌注桩相比 ,它能够大幅度提高单桩承载力 ,具有明显的经济效益。通过对大量的挤扩支盘桩竖向承载力试桩资料的分析 ,提出了新的挤扩支盘桩竖向极限承载力经验公式 ,并验证了该公式的适用性

关 键 词:挤扩支盘混凝土灌注桩  单桩竖向承载力  经验公式

Abstract:An extruding pile with branches and plates is the one deriving from the ordinary cast-in-situ concrete piles, by which the bearing capacity of a single pile can be raised substantially with a remarkable economic benefit. A new empirical formula is proposed for vertical ultimate bearing capacity of the extruding pile with branches and plates by analysing a lot of test pile data of the extruding piles with branches and plates, whose applicability is also verified.
Keywords:cast-in-situ  concrete pile with branches and plates vertical bearing capacity of single pile empirical formula
