摘　　要：针对目前我国桥梁工程基础设计中运用比较多的AM全液压可视可控旋挖钻孔扩底桩的工艺特点,对其造价进行分析。结合天津市芥园西道立交工程实例,经分析得出扩底桩符合我国节能环保政策要求,建议在条件允许的情况下推广使用。Focusing on the fact that the AM full hydraulic visual controllable rotary drilling under-reamed bored pile technology is frequently-used in the basic design of bridge engineering in China,this paper analyzes engineering cost with the example of Jieyuan west road interchange project in Tianjin,proposes that underreamed bored pile is in compliance with the requirements of China＇s government＇s policy of energy conservation and environment protection,and should be recommended in case of promise.

关 键 词：扩底桩 造价分析 节能环保 桥梁工程
