The dredge and survey platform including a series of sampling,sampling preparation and vacuum preloading model test devices is designed and developed which can execute exploration,sampling and monitoring in reclamation soft soil.Taking a series of means including drilling and sampling,settlement monitoring,indoor soil test,model test and so on,combining physical index method,layerwise summation method,one-dimensional finite strain method of reclamation soil，and some settlement computation methods of in-situ soil and software calculation system,a software and hardware prediction system of reclamation elevation in reclamation area is formed.The system is used in a reclamation area behind 6#～8# berth in Binzhou port.The result shows that the reclamation elevation shall not be less than 8.55 m if the foundation will be treated by vacuum preloading method and the elevation should reach 3.5 m after treated .
