Abstract: The traditional electroosmotic energization mode generally inputs the electrical current into the upper part of the anode and the cathode. One of the problems is that the lower part of the electrode is seriously corroded, and the strength of the soft soil is not uniformly improved. To solve this issue, a staggered current mode is proposed, and the effectiveness of this mode is verified throughout experiments. In this paper, two silt peaty soil electroosmosis samples are prepared; one is prepared by using the traditional energization mode and the other is using the staggered energization mode. The test results show that: (1) under the same water discharge conditions, the energy consumption of the staggered energization mode is reduced by about 23% compared with the traditional energized mode; (2) Compared with the traditional current mode, the cumulative water discharge in the staggered current mode is increased by about 60%; (3) Using the staggered energization mode, the shear strength of the soft soil after the improvement is increased by about 80% compared with the traditional energization mode. The improvement result in soil mass is more uniform. This test proves that the staggered energization mode has a better improvement effect and lower energy consumption, which can provide a good reference for the future research and practical projects.
