摘要
以港口码头护堤内部缺陷检测为例,基于不同地球物理技术特点,提出地质雷达、高密度电法和地震映像法的综合物探无损检测方法。研究表明,基于3种浅层物探技术资料解释,利用多方法相互比对验证,可有效解决单一技术多解性难题,准确探明结构体内部缺陷隐患类型、位置、规模等参数,为护堤维修加固和安全评估提供有效依据。
This study takes the detection of internal defects in port pier embankments as an example,and proposes a comprehensive geophysical non-destructive testing method based on the characteristics of different geophysical technologies,including geological radar,high-density electrical method,and seismic imaging method.The research shows that based on the interpretation of data from three shallow geophysical techniques and the use of multiple methods for mutual comparison and verification,the problem of multiple solutions for a single technique can be effectively solved.The types,locations,and scales of internal defects and hidden dangers in the structure can be accurately identified,providing an effective basis for the maintenance,reinforcement,and safety assessment of embankments.
