摘要
从能量的角度出发,提出了土体电渗固结的能级梯度理论,并结合试验,对电渗过程中的电学问题进行较为详细的分析,给出了土体电渗过程中的电流、电势、电势差以及土体电阻率的分布和变化规律. 基于能级梯度理论,还给出了电渗流量、孔隙水压力、固结沉降以及电渗能耗的表达式,并对照传统的Esrig理论,分析和讨论了二者之间的异同点.
From aspect of energy consumption, an electro-osmotic consolidation theory named energy level gradient theory is brought out in this paper, and detailed electrical analyses on electro-osmotic process are completed in the light of experiments. The analyses interpret the distribution and variation pattern of electric current, electric potential, difference of potential and electrical resistivity of soil in the electro-osmotic process. Based on energy level gradient theory, formulae of electro-osmotic drainage, pore water pressure, consolidation settlement and electrical energy consumption are also presented in this paper. Comparing them with those formulae in the Esrig theory, the author also give some analyses and discussion to show the similarities and differences between these two electro-osmotic consolidation theories.
