Abstract The dynamic compaction with low energy was considered to deal with the problems of the increasing of the electrical resistance of soil samples due to cracking and of the interface between anode and soil，the increasing of energy consumption and the decreasing of the effect of consolidation due to anode corrosion in the electro- omostic process，and in the extreme cases the interruption of the electro-osmotic process. Indoor model tests of electro-osmosis with and without the low-energy dynamic compaction were carried out respectively. The low energy dynamic compaction was found to improve the drainage paths of the soil and the water drainage was increased than that without dynamic compaction. The electrical circuit current was increased and soil compactness was enhanced due to low-energy dynamic compaction. The cracks in soils ample was closed，the surface settlement was increased，and the uneven settlement of soil and the anode corrosion were reduced due to the low-energy dynamic compaction. Suggestions of carrying on dynamic compaction in the cracking soil of anode zone were thus made for application in the engineering practice. Dynamic compaction should start when the water flow become smaller and the anode zone become dry.

Key words： soil mechanics low-energy dynamic compaction electro-osmosis compactness settlement drainage path
