土体中电现象的应用

介绍了5种主要的土体电现象，及其在加筋，固结，环境治理等方面的应用，并对土 的电渗固结进行了理论分析，由此得出：在施加电场的情况下，孔压消散加快，随着时间的增加，孔压可以达到负值，另外，土体固结度增加，相应的土体电动固结后的含水量低于加载固结，这些结论与NettletonI.M.的一系列试验结果比较吻合。

Electrokinetic phenomena in soil and their applications

Some kinds of electrokinetic phenomena in soil together with their applications in the field of reinforcement, consolidation, and environment regulation are introduced. Then a theoretical analysis is made, and some conclusions are drawn: under the action of an electric field, the dissipation of pore pressure speeds up; with the increase of time, the pressure can be a negative value; with the increase of soil consolidation, the water content in soil under electrokinetic consolidation is smaller than that under loading consolidation. The conclusions are in good agreement with the results from a series of experiments done by Nettleton I M, et al in 1998.
