| 摘 要： | 对汛期时实现堤坝的实时监测进行实验模拟,以验证该监测方法可行。利用网络并行电法仪采集自然电位场、激励电位场以及电流场。通过模型不同时间的数据比较,发现当有水进入孔洞时模型的自然电位和一次场电流有明显的增大,一次场电位显著减小,而电阻率随着模型含水越来越多逐渐减小,可以确定此处存在渗水的空洞或裂隙,实验效果明显。对预防堤坝孔洞或裂隙渗水事故具有实际指导意义。 |

| Abstract: | In order to prove that this monitoring method is feasible,the experimental simulation for real-time monitoring detection of the dam is made in flood season.Network parallel electrical equipment is adopted to collect the natural potential field,incentive potential field and current field.Through data comparison at different times,the natural potential field and current field increased evidently when the water flowed into the hole,and incentive potential field reduced significantly,but the resistivity decreas... |
