Bearing Capacity of Basements and Stability of Slopes Formed by Flooded or Air-Dry Sandy Soils

详细

We present the results of measurements of the bearing capacity of basements and the stability of the slopes in sands in the air-dry state, in the presence of capillary humidity, and in the case of flooding, when there are no water menisci in the pores and the sand is suspended in water, carried out under laboratory conditions. The results of the tests demonstrate that the strengths of flooded and air-dry sandy soils are much lower than in the presence of capillary humidity. It is proposed to take into account the specific weight of soils suspended in water in the numerical analyses of the stability of flooded slopes.
