摘　　要：比较桩顶平头桩和外伸钢筋桩2种方案的施工工艺和经济效益,证明桩顶采用平头桩比传统的外伸钢筋桩的综合效益要好。尤其在沉桩施工时,沉桩的效率更高,桩身质量保证率更好。Through comparing the construction technology and economic benefit between fiat-head piles and reinforced bar out-stretching piles, it is proved that the comprehensive benefit of fiat-head pile is better that that of traditional reinforced bar out-stretching piles, esp., piling construction of the ＂fiat-head＂ is more efficient than that of ＂out-stretching ones＂ and quality of pile body is better guaranteed.

关 键 词：预制方桩 桩顶 效益 质量
