【摘要】 直流电法广泛应用于资源探查、建筑工程、野战给水等的地下情况探测,但其探测异常体的深度仍存在不一致的认识。为研究其探测深度的影响因素,设计水槽模型实验,利用联合剖面装置及对称四极装置(验证作用)对低阻体进行探测,综合考虑诸多因素,重点研究了电极对联合剖面法的探测深度影响。经实验得出,固定AB/2,MN/2越小,则探测越深,精度越高;且联合剖面法在横向上和垂向上的分辨率都较高,且在垂向上更准确,在横向上确定异常体的位置时会发生一定的偏移;联合剖面法所得的曲线最小值的连线代表异常体的倾斜方向。对联合剖面法探测异常体的埋深确定提供了一定的参考依据。更多还原

【Abstract】 Direct current electric method Widely used in resource exploration,constructional engineering,water supply and so on for their subsurface terrain.However.there’s still no consistent understanding of the detection depth.For researching influence factors of depth,design tank model test In this paper,using symmetrical quadruple device and joint profile device(for verifying role).Considering many factors and focusing on the influence of electrode on the depth of detection.By the experiments,confirming AB/2,changing and reducing MN/2,then,getting the deeper the detection and Higher precision.Joint profile device has higher resolution in horizontal and vertical detection.And vertical detection is more accurate than horizontal one.The minimum of results of Joint profile device represents direction of the anomalous body.In this paper,the detection depth to provide certain reference basis.更多还原
