摘要:
针对海洋泥沙掩埋对电场测量的影响,采用镜像法推导了海水中水平电偶极子在海床介质层中产生的电场,利用该理论公式计算了不同掩埋深度、不同泥沙电导率情况下的电场值,结果表明泥沙掩埋会导致同一位置处的电场峰峰值降低,且泥沙电导率越低,电场衰减比例越大。最后在实验室水池进行了长期泥沙掩埋监测试验,结果表明泥沙掩埋会对测量电极的静态电位差产生一定的影响;对于1~10 Hz的电场信号,泥沙掩埋之后会导致所测得电场信号峰峰值降低,且掩埋深度越大、掩埋时间越长,降低越明显。
Abstract:
To study the influence of marine sediment burial on electric field measurement, firstly, the electric field in the seabed layer generated by a horizontal electric dipole in seawater was deduced based on the image method, then the electric field under different burial depth and different sediment conductivity were calculated. The results showed that sediment burial caused the reduction of the peak value of electric field, and the lower the conductivity of the sediment, the larger the attenuation ratio of electric field. Finally, an experiment of sediment burial was carried out in a laboratory water tank for a long time. The results showed that sediment burial would affect the static potential difference of the measuring electrodes. For the electric field between 1~10 Hz,the peak values of the electric field measured at different burial depths were lower to those before burial,and deeper burial depth and longer burial time would lead to more reduction.
