摘要

    摘要
  • 摘要: 利用改进的一维电渗固结试验装置对饱和软黏土进行电渗试验，通过监测电渗过程中的电流、电压、电势、排水量、电渗前后的含水率和抗剪强度，利用电渗透系数、电迁移系数、能耗系数来研究不同电源输出方式下的电渗排水状况。试验结果表明：相比于稳压输出方式，压流模式下的累积排水量更小且排水速率更慢，有效电势利用率变化幅度略小，电渗透系数和电迁移系数衰减得更快，含水率的总下降值和归一化抗剪强度略大；相比于稳流输出方式，流压模式下的累积排水量更大且排水速率更快，有效电势利用率变化幅度更小，电渗透系数和电迁移系数衰减得更慢，含水率总下降值和归一化抗剪强度更大。通过对不同电源输出方式下能耗系数递增速度的对比，得出流压模式下电渗工况更经济合理。
    Abstract: One-dimensional electroosmotic laboratory test was conducted in saturated soft clay under one dimensional electroosmotic consolidation test device, by monitoring current, voltage, potentials, the amount of drainage in the process of electroosmosis, and initial and final moisture content and shear strength, electrical permeability coefficient, electric migration coefficient, energy consumption coefficient were used to study electroosmotic drainage condition under the way of different power output.The test results showed that compared to stabilized output way of voltage, the cumulative amount of drainage was smaller and drainage rate was more slowly, change amplitude of effective potential utilization rate was slight, electric coefficient of permeability and electric migration coefficient decay were faster, and the overall decline value of the moisture content and normalized shear strength were slightly larger in the mode of the voltage and current.Compared to the mode of constant-current output, cumulative displacement was larger and drainage rate was faster, change amplitude of effective potential utilization rate was small, electric coefficient of permeability and electric migration coefficient attenuation were more slowly, and the overall decline value of the moisture content and normalized shear strength were larger in the mode of current and voltage.By contrasting to energy consumption coefficient under the different way of hybrid power output, drawing the electroosmosis condition in the mode of current and voltage was more economic and reasonable.
