CONSOLIDATION TEST AND STUDY ON THE TREATMENT OF DREDGE FILL WITH CEMENT AND LIME

With the development of economy in coastal areas of Southeast China, the problem of land lacking becomes prominent. A technique for land with dredge fill is a new way to solve the problem. In order to reduce time of consolidation of dredge fill, we made a sedimentation test of dredge fill and tried to find a method for consolidating the dredge fill while dredging. During the test it was found that the result of consolidation with mixed cement with lime is better than that only with cement. Comparing the engineering geological properties of soil samples and analyzing the structure of soil samples and other results of physical and chemical tests, we found the causes for different of consolidation results, so we can provide a more economical method to consolidate foundation of dredger fill.
