为了研究土体含盐量对软黏土电渗排水的影响,在自制的试验槽里进行室内一维试验,利用试验数据从排水量、排水速率、能量消耗、含水率和电化学反应等5方面对电渗性状进行对比分析。试验结果表明:含盐量对软黏土电渗性状有着明显影响,并存在最佳含盐量;较高的含盐量不利于电渗排水和含水率降低,而且会导致能量消耗、阳极腐蚀量和电渗后酸碱不平衡较大;能量消耗系数、阳极腐蚀百分比和排水速率与电流强度的比值这3者都与土体含盐量存在一定的定量关系。试验结果能为判别电渗的工程适宜性提供一定的参考依据。
In order to study the effect of soil salinity on the electro-osmotic drainage of soft clay, a one-dimensional indoor test was carried out in a self-made test tank. The test data were used to evaluate the effect of salt content on the electro-osmotic drainage of soft clay from the aspects of displacement, drainage rate, energy consumption, water content and electrochemical reaction Comparative analysis of electro-osmotic traits. The results show that the salt content has a significant effect on the electroosmotic properties of soft clay, and the optimum salt content exists. Higher salt content is not conducive to the electro-osmosis drainage and moisture content reduction, but also lead to energy consumption, anode corrosion And acid-base after the electro-osmosis large imbalance; energy consumption coefficient, the percentage of anodic corrosion and drainage rate and the current intensity ratio of the three with soil salt content there is a certain quantitative relationship. The test results can provide certain reference for judging the engineering suitability of electroosmosis.
