【 摘 要 】

The building is stable if it's able to withstand the load above and slightly decreasing soil. In development planning it is necessary to the condition of the soil to avoid building construction failure so it needs to be tested first. Plasticity soil can have high expansive or shrinking properties depend on the amount of water content and the type of soil minerals contained. The level of expanding and contracting the soil will have an impact on soil subsidence. The velocity of the land subsidence is calculated using the consolidation coefficient results from the consolidation test. Consolidation is a process of slowing down the volume slowly on perfectly saturated soils with low permeability due to pore drainage. The study aims to determine the bond of the plasticity index with the consolidation coefficients of the samples obtained.so that it is known the speed of land settlement due to the burden borne by the soil. Soil samples were taken by maintaining the original properties (undisturbed sample), then tested the physical properties and mechanical properties of the consolidation test. Based on the results of the processing of index plasticity and consolidation coefficient it is found that the greater the plasticity index, the smaller the coefficient of consolidation. So that the magnitude of the plasticity index has a proportional bond to the speed of land subsidence.
