Abstract

Model test of long-term drainage consolidation model of floating mud was carried out in this paper. The test was carried out in a large consolidation model test tank developed by the laboratory itself. The test reinforcement period is 691 days. After the reinforcement by a preloading load of 80kpa, the final pore water pressure is close to zero which indicates that the floating mud basically complete the main consolidation. The latter stage settlement is mainly secondary consolidation settlement. Under the condition that the soil is basically completely consolidated, the ultimate shear strength of the cross plate is only 13.1kPa, which is still not ideal. The settlement of the floating mud with little strength and high water content at the beginning is very large after drainage consolidation and the strength increase is also very large. However, the absolute value of the strength after reinforcement is relatively low. It should be paid attention to by the engineering community.
