Evaluation on the Effect of Dynamic Compaction Based on Multistage Fuzzy Synthetic Judgment

There are many indexes for testing the dynamic compaction effect of lager-scale engineering which cause great difficulties for the comprehension evaluation of the effect. Based on the single factor evaluation and the rationalization of the weights for various factors, a multistage model for fuzzy comprehensive evaluation is set up for the dynamic compaction effect evaluation of the dredger fill. The result is scientific and reasonable. The method has the advantages of low cost, easy application with remarkable effect in short construction period, and it may be a reference for the design and field evaluation of harbor, embankment and airport runway.
