| Abstract: | The formula of preloading time of eliminating primary consolidation under charge is worked out, taking the deformation of second consolidation caused by preloading of soft soil surcharge into account. The influences of different surcharge amounts and different surcharge preloading time on saturated soft-soil second consolidation are researched through laboratory tests , which is useful for soft soil ground treatment with draining consolidation method. |

| Keywords: | surcharge preloading consolidation degree second consolidation deformation |
