摘要
文章结合钻孔扩底灌注桩在某桥梁基础中的成功应用,对钻孔扩底灌注桩的成桩原理进行了相关的阐述,为确保钻孔扩底灌注桩桩端扩大头的施工质量,根据其自身特点,提出采用传统的钻孔取芯法进行检测,并针对工程应用情况进行了定性评价。
According to successful application of bored pile in a bridge, construction principle of under-reamed bored pile is discussed in details. A simple and traditional method borehole sampling is suggested to knowledge the quality on enlarged end of pile according to its characteristic, and the qualitative analysis is given in connection with engineering application.
