The dredger fill dewatering effect of vacuum preloading incorporated with electro-osmosis in different ways was evaluated by implementing six laboratory tests. The results of these tests show that the asynchronous consolidation effect of vacuum preloading incorporated with electro-osmosis was better than the other tests. However, vacuum preloading and electro-osmosis will not be able to give full play to the drainage effect, if the alternate time is too short. Alternatively, the energy provided by vacuum preloading and electro-osmosis will not be able to make full use, if the alternate time is too long. There are some advantages when using vacuum preloading and electro-osmosis asynchronous reinforcement. The alternate time of vacuum preloading and electro-osmosis has to constantly adjust according to the water discharge or drainage rate in engineering application.
