以传导类电法勘探原理形成的走航式电法快速探测技术,采用迫近目标体的水下单极供电、多个测量电极线性排列测量电位的方式对水底隐患或掩埋良导目标体进行探测.利用ANSYS软件进行有限元数值模拟的结果表明:探测顶部离水面14m、半径5m的良导球体,当与水平电极系所在直线重合的测线过球顶正上方且距球心9m时,电位相对异常极大值超过8%;水槽物理模拟结果与数值模拟结果很好地吻合,综合验证了走航式电法快速探测技术的有效性.所测数据无需视电阻率转换,同时整套测量系统具有装置灵活与测量快速的特点,适合对江河堤坝和库区渗漏隐患以及水底金属结构物进行快速探测.
Based on the rapid aeronautical detection method based on the principle of conduction-type electrical exploration, underwater submarine or well-buried target is probed by underwater unipolar power supply approaching to the target and multiple measurement electrodes linearly measuring potential The results of finite element simulation with ANSYS software show that when a good guided sphere whose top is 14m away from the water surface and radius is 5m, when the line coinciding with the line where the horizontal electrode system is located is above the dome and 9m away from the center of the sphere, the potential The relative maximum value is over 8%. The physical simulation results of the flume are in good agreement with the numerical simulation results, which verify the effectiveness of the rapid aeronautical detection technology. The measured data do not need the apparent resistivity conversion, With flexible device and fast measurement, it is suitable for rapid detection of seepage hazards and underwater metal structures in river banks and reservoirs.
