| 摘 要： | 针对支盘桩相对于普通等截面直孔灌注桩具有较高承载力的特性,采用自平衡静载荷试验方法,分别对浙江嘉兴和湖州两个工程中的同一场地支盘桩与普通直孔桩进行对比试验研究.试验结果表明,在同等工程地质条件下,采用支盘桩能提高极限抗拔承载力,并可减少桩径和缩短桩长,具有良好的经济效益.

| Abstract: | Compared with the column bored pile, the compaction-under reamed bored pile is a new type of piles with higher bearing capacity, The comparative tests related to the ultimate bearing capacity of both compaction-under reamed bored pile and column bored pile at the equal sites of Jiaxing and Huzhou of Zhejiang province in China were studied by using the self-balanced method under static pressure ,The result testifies that compaction-under reamed bored piles can obtain better economic benefit under the same geological conditions, such as increasing the ultimate extraction bearing capacity of piles and redueing diameter and length of piles. |

| Keywords: | compaction-under reamed bored pile self-balanced method ultimate extraction beating capacity comparative test |
