INDOOR EXPERIMENTAL RESEARCH ON VACUUM PRELOADING COMBINED WITH EKG ELECTROOSMOTIC METHOD
Vacuum preloading combined with electroosmosis can give full play to the respective advantages of vacuum preloading and electroosmosis,and is a very potential soft ground treatment technology,and EKG is one of the commonly used electrode materials for electroosmosis.In order to study the effect of different electrode materials and energization methods on the drainage effect of vacuum preloading combined with electroosmosis,an indoor one-dimensional model test was carried out based on EKG electrodes,and a metal electrode was set as a control to study the drainage consolidation under different materials and energization methods.The drainage effect of vacuum preloading combined with electroosmosis at different reverse voltages was further explored through supplementary experiments.The test results show that:under the test conditions in this paper,the overall electroosmotic drainage effect of the EKG electrode in the three modes of continuous energization,intermittent energization and reverse energization is better than that of iron,aluminum and copper electrodes;when EKG,aluminum and copper electrodes are used.When using the electrode,the soft soil drainage potential can be activated by using the intermittent energization mode for the soft soil,and the drainage volume can be increased;when the EKG electrode is used,the appropriate reverse voltage can be selected to effectively promote the drainage consolidation of the soft soil,and obtain more than continuous.Drainage effects in both energized and intermittent energized modes.
