摘　　要：为了探明南京大河口段长江堤防出现渗漏险情的原因,在该堤段布置3条长度为800m的测线,利用探地雷达沿着测线对堤防进行隐患探查,共发现36处地质异常区域,包括30处不密实缺陷区域与6处裂缝缺陷区域。采用防渗处理、白蚁灭治、道路与绿化恢复等措施对发现地质异常区域的堤段进行消险,有效提高了堤防的整体性与防渗能力,减缓了坡面侵蚀与塌陷速度。探地雷达是一种高效、无损的隐蔽工程隐患探查方法,能够为水利工程人员辨别堤防安全状况提供可靠的数据与技术支撑。To investigate the causes of leakage hazards in the Nanjing Dahekou section of Yangtze River embankment,three 800 meters long survey lines were arranged along the embankment section.Using ground penetrating radar to explore hidden dangers along the survey line of the embankment,a total of 36 geological anomaly areas were discovered,including 30 areas with loose defects and 6 areas with crack defects.Measures such as anti-seepage treatment,termite control,road and green restoration were taken to eliminate risks in the embankment sections where geological anomalies were found,effectively improving the overall integrity and anti-seepage capacity of the embankment,and slowing down the erosion and collapse speed of the slope surface.Ground penetrating radar is an efficient and non-destructive method for detecting hidden engineering hazards,which can provide reliable data and technical support for water conservancy engineering personnel to identify the safety status of embankments.
