Mechanical properties of sandy soil at different depths
Conclusions 1. Loading tests of soil with a plate set at different depths, with measurement of the settlement of the plate itself and of the surrounding ground surface, and with determination of the ratio between total and restorable settlement, permits one to obtain very complete information on the mechanical properties of the soil and to find a basis for selecting the most appropriate model of a foundation bed. 2. The characteristics of soil compressibility may be determined from the results of impression of a plate in accordance with the method proposed by N. A. Tsytovich and I. I. Cherkasov. 3. The compressibility of the investigated sands depends on the external load on the test plate and the depth of the horizon being tested. 4. The coefficient of compressibilitya0 of the investigated soils declines with depth and increases with increase in test load on the plate. 5. The modulus of general strain $ E_{0} $ and the modulus of subgrade reaction $ c_{Z} $ of shallow sands increase with depth and decrease with increase in load on the test plate. 6. The relation of compressibility of the investigated sands to load varies with depth, changing gradually from a nonlinear law to practically a linear law. 7. The most suitable design model of a foundation bed for the investigated conditions is linearly deformable half-space with a strain modulus that increases with depth.
