为研究不同补水边界条件对电渗加固软土地基效果的影响,在自制的试验装置上对高岭土进行了不同补水边界条件的电渗固结试验,通过监测电渗过程中电流、电势、排水量、抗剪强度、含水率和沉降等指标,发现不补水条件下的电渗加固软土效果优于补水条件下的电渗加固效果;在不补水条件下软土通过电渗加固还会出现较大裂缝,表明不同的补水边界对电渗加固效果影响较大,在电渗室内试验时必须考虑补水边界条件的影响。
In order to study the influence of different water supply boundary conditions on the effect of soft soil foundation strengthened by electroosmosis, the kaolins were tested on the self-made test device by electro-osmosis consolidation with different water supplementing boundary conditions. By monitoring the current, potential, displacement, Shear strength, moisture content and settlement and other indicators, it is found that the effect of electro-osmosis reinforced soft soil under non-recharge condition is better than electro-osmosis reinforcement effect under the condition of recharging water; Cracks, indicating that different recharge boundaries have a great influence on the effect of electro-osmosis reinforcement. The influence of recharge boundary conditions must be considered in the electro-osmosis chamber test.
