The utility model discloses an experimental device for simulation vacuum pre -compaction in -process ground water level change, including model groove, the vacuum pumping system that is connected with the model groove, the model inslot contains gravel sand to the transverse drainage body and the vertical drainage body have been laid at the model inslot, the external parcel of vertical drainage has geotechnological cloth, the model inslot is equipped with geotechnological cloth, a reinforcement district is separated to geotechnique's cloth, just the even layering of district's soil body wall will be consolidated along vertical to geotechnique's cloth, cover the top and have the geomembrane in the reinforcement district, bury simple and easy fluviograph respectively inside and outside consolidating the district. The utility model discloses can be in the indoor situation of change of simulating the on -the -spot ground water level of vacuum pre -compaction proximately, the soil body of the corresponding osmotic coefficient of geotechnological cloth simulation that can be through changing different osmotic coefficients to relation between the more convenient situation of change of probing vacuum pre -compaction in -process soil body osmotic coefficient and ground water level.
