摘要
各种自然或人为因素导致堤防工程普遍存在渗漏隐患,汛时易导致险情发生,因此有必要进行隐患探测.高密度电法作为一种无损检测手段,能够有效对堤防渗漏段进行勘察.文中以江西某堤防工程为例,通过分析视电阻率剖面,发现可能存在的渗漏通道,极大提高了现场检测工作效率.实践证明,采用高密度电法能快速、准确探测渗漏通道情况,可推广使用.
Numerous natural and human factors can cause hidden defects in embankments, resulting in dangerous situation during flood period, hence it＇s necessary to conduct hazard detection. High - density electrical method as a non - destructive testing technique can effectively investigate the leakage section of the embankment. It＇s utilized in this paper the high - den- sity electrical method to search for the possible leakage passage in a certain embankment in Jiangxi and the practice shows that this method can effectively and accurately detect the passage and well worth promotion.
