摘　　要：钻孔灌注桩具有施工噪声小、抗震能力强的优点,在桥梁施工中占据重要地位。以通锡高速海门至通州段工程项目桥梁桩基施工为背景,试验研究泥浆比重对超声波检孔数据采集的影响,结果表明,泥浆比重越大,灌注桩的成孔质量越差。Bored cast-in-place piles have the advantages of low construction noise and strong seismic resistance,occupying an important position in bridge construction.Taking the bridge pile foundation construction of the Haimen to Tongzhou section of the Tongxi expressway project as the background,an experimental study was conducted to investigate the influence of mud specific gravity on the collection of ultrasonic inspection hole data.The results showed that the higher the mud specific gravity,the worse the quality of the bored pile.

关 键 词：钻孔灌注桩 超声波检孔 数据采集
