为了在电渗设计阶段选择合适的电极间距和长度,采用土体各向同性假设,推导排形布置电渗电极的三维电场强度计算式,并比较不同电极间距和电极长度下电场特性,分析每对电极的电场影响范围。然后,考虑相邻电极对的影响,对电场进行简化。最后以工程实例说明推导方法的应用。结果表明:利用电场强度计算式,在电渗设计阶段可利用设计电渗排水速率来选择合适的电极间距、长度和排距,以满足技术和经济的要求。
In order to choose the appropriate electrode spacing and length in the electro-osmosis design stage, the three-dimensional electric field strength of electrosurgical electrode was deduced based on the assumption of isotropy of soil. The electric field characteristics of different electrode spacing and electrode length were compared. The electric field of the electrode affects the range. Then, taking into account the influence of adjacent pairs of electrodes, the electric field is simplified. Finally, the engineering examples illustrate the application of the derivation method. The results show that by using the formula of electric field intensity, the design of electroosmotic drainage rate can be used to select the appropriate electrode spacing, length and row spacing in the electroosmotic design stage to meet the technical and economic requirements.
