【摘要】 为了对液压挤扩支盘桩的工程特性做进一步研究,在黄河三角州地区对普通桩、支盘桩、分支桩进行了静载试验,分析了它们的极限承载力、单方混凝土承载力及桩顶荷载传递规律,结果表明：在相同地质、相同直径条件下,分支桩的极限承载力和单方混凝土极限承载力高于普通灌注桩；支盘桩的承载力和单方混凝土极限承载力高于分支桩；在荷载传递过程中,分支和支盘分担了大部分荷载,桩段只承担小部分荷载。更多还原

【Abstract】 The bearing capacity of the squeezed pile with the expanded branches is studied in this paper. Through the static loading test in Shandong province,the bearing capacity of three kinds of squeezed pile is compared.According to the stress of the reinforced bar,the force of different places of the pile is obtained, and the rules of the load-transfer are studied.It is deduced that the bearing capacity of the dish pile is larger than the branch piles and the general pile.In the process of the load-transfer the dish and the branches play important roles.更多还原
