摘要
为提升桥梁桩基检测技术水平,文章总结了声波透射法、钻芯法检测桩基的原理,从声测管布置、系统延迟时间标定、判据确定、钻孔布置、钻芯取样要求及芯样截取和抗压试验等方面分析了桥梁桩基综合检测技术要点,并以某公路桥梁1#桩基为研究对象,制订了检测方案,以供参考。
In order to improve the technical level of bridge pile foundation testing,this paper summarizes the principle of crosshole sonic logging and core drilling method for pile foundation testing.The key points of bridge pile foundation comprehensive testing technology are analyzed from the aspects of sonic logging pipe arrangement,system delay time calibration,criterion determination,drilling hole arrangement,core drilling for sampling requirements,core sample interception and compression test.Taking the 1#pile foundation of a highway bridge as the research object,the testing scheme is formulated for reference.
