Permeability characteristics of biotite granitic weathered soil under different consolidation pressures
In this paper,two different types of remodeled soil samples were prepared from the completely weathered biotite granulite weathered soil in Sijiaying,Tangshan City,and the consolidation permeability test of the remodeled soil samples was carried out by using a self-made permeameter. Under different consolidation pressures,the permeability coefficient of reshaped soil samples was determined,and the influence of consolidation pressure on the permeability coefficient of soil samples was analyzed. The test results show that with the increase of consolidation pressure,the soil sample is continuously compressed,and the maximum compression amount of soil sample reaches when the consolidation pressure is 800kpa. With the increase of consolidation pressure,the permeability coefficient of soil samples gradually decreases.
