【摘要】 为了研究电渗过程中土电阻率的变化规律,在阐述了土电阻率相关理论的基础上,将三种不同塑性指数的土配置成初始含水率大致相等的试验土样,利用改进后的Miiller Soil Box进行室内电渗试验,并利用四相电极法测量电渗过程中试验土体的电阻率。分别记录三种土样在试验过程中的排水量、含水率、电阻率等参数,基于土体电阻率相关理论分析发现电渗过程中试验土体塑性指数大小对电阻率变化规律有明显影响并结合试验现象得出了描述三种试验土样含水率和电阻率的变化的拟合函数。更多还原

【Abstract】 In order to study the variation law of soil resistivity. Based on the theory of soil resistivity,the soil with three different plastic index is arranged into the test soil sample with approximately equal initial water content. The indoor electro osmotic test was carried out with the improved Miiller Soil Box,the resistivity of the soil in the electro osmotic process was measured by two phase electrode,water discharge water content and resistivity of three soil samples was recorded,variation law of soil resistivity with different plasticity index in electro osmotic process was analyzed based on theory of soil resistivity,and the fitting function of water content and resistivity of three kinds of soil samples was derived under the condition of electroosmosis.更多还原
