RESEARCH ON EMPIRICAL FORMULA FOR SINGLE PILE VERTICAL BEARING CAPACITY OF CAST-IN-PLACE CONCRETE PILES WITH BRANCHES AND PLATES
-
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。

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. -
