Soil Mechanics and Foundation The ultimate consolidation settlement of a structure resting on a soil Increases with the increase in the initial voids ratio Decreases with the decrease in the plastic limit Increases with the decrease in the porosity of the soil Decreases with the increase in the initial voids ratio Increases with the increase in the initial voids ratio Decreases with the decrease in the plastic limit Increases with the decrease in the porosity of the soil Decreases with the increase in the initial voids ratio ANSWER DOWNLOAD EXAMIANS APP
Soil Mechanics and Foundation Due to a rise in temperature, the viscosity and the unit weight of the percolating fluid are reduced to 60% and 90% respectively. If other things remain constant, the coefficient of permeability increases by 50% increases by 25% decreases by 33.3% increases by 33.3% increases by 50% increases by 25% decreases by 33.3% increases by 33.3% ANSWER DOWNLOAD EXAMIANS APP
Soil Mechanics and Foundation Coefficient of compressibility is different for different types of soils but same for a soil under different states of consolidation independent of type of soil but depends on the stress history of soil different for different types of soils and also different for a soil under different states of consolidation constant for any type of soil different for different types of soils but same for a soil under different states of consolidation independent of type of soil but depends on the stress history of soil different for different types of soils and also different for a soil under different states of consolidation constant for any type of soil ANSWER DOWNLOAD EXAMIANS APP
