摘要: 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。Abstract: Based on the assumption of homogeneous isotropic soil and ignoring the dimensions of electrodes,the formula for three-dimension electric field intensity by parallel rows of electrodes was proposed.The characteristics of electric field under different spacing between opposite polarity electrodes and electrodes lengths were compared.Influence scope of electric field was also investigated.Then electric field intensity formula was simplified by considering the effect of adjacent electrode pair.Finally,the application of the theory was illustrated with the combination of case history.Parameters analysis shows that appropriate electrodes parameters can be selected in the electro-osmotic design phase by the electric field intensity formula to meet technical and economic demand.
