摘　　要：基桩质量关系到上部结构的正常使用安全。本文以钻孔灌注桩质量检测为背景,采用声波透射法对桩身质量进行初步完整性检测分析,然后借助钻芯法对桩身疑似缺陷部位进行验证检测,并对缺陷部位进行注浆加固处理后再复检。通过注浆加固处理前后基桩质量的检测结果对比分析,验证了多手段检测基桩质量的必要性和注浆加固处理措施的可行性,为后续类似基桩质量检测及注浆加固处理提供借鉴。The quality of foundation piles is related to the normal use and safety of the upper engineering structure,and its importance is self-evident.This paper takes the quality inspection of engineering foundation piles as the background,and uses the acoustic transmission method to conduct preliminary inspection and analysis of the pile body quality.Then,using the drilling core method,the suspected defect parts of the pile body are verified and tested,and the defective parts are grouted reinforcement before retesting.By comparing and analyzing the testing results of the quality of foundation piles before and after grouting reinforcement treatment,the necessity of multiple methods for detecting the quality of foundation piles and the feasibility of grouting reinforcement treatment measures were verified,providing reference value for similar foundation pile quality detection and grouting reinforcement treatment in the future.
