基于分段线性化的泥浆一维电渗脱水模型
One Dimensional Electroosmotic Dewatering Model of Mud Based on Piecewise Linearization
摘要
Abstract
Based on piecewise-linear method,a one-dimensional electroosmotic dewatering model of mud was pro-posed in order to further explore the influence factors of mud electroosmotic dehydration.In this model,the com-bined influence of potential gradient and void ratio on the electroosmotic coefficient of mud and the nonlinear stress-strain relationship and large deformation effect of mud were considered.Compared with the results of relevant ana-lytical solutions and laboratory model tests,the error of this model was less than 5%.On this basis,the influences of loading voltage,compression index and electroosmotic coefficient on the process of mud electroosmosis dehydra-tion were analyzed.The results showed that the increase of loading voltage and electroosmotic coefficient could im-prove the final water removal and shorten the stabilization time.With the increase of mud compressibility,the final dewatering volume of mud increased,but the stabilization time was prolonged.关键词
