Marchenko V. Stress-deformed state of weak clay bases reinforced by boring and mixing technology taking into account the time factor

Object - the base, formed by weak saturated clay soil, reinforced by vertical soil-cement elements, made on boring and mixing technology; purpose - evaluating of changes in the stress-strain state of reinforced by boring and mixing technology weak clay bases of plate foundations considering the time factor; methods - plate bearing testing of soil bases in the tray, standard laboratory methods for determining the characteristics of soils, field plate bearing tests of reinforced bases, surveying, observation of building settlements on reinforced bases, mathematical simulation of SSS of reinforced bases using FEM and elastic-plastic models of soil; innovation - received new experimental dependences of the stress-strain state of weak clay bases reinforced by boring and mixing technology and percentage, depth of reinforcement, the density of the soil skeleton, cyclic loading of base; the results - the method of calculating of weak saturated bases of granaries reinforced by soil-cement elements considering the time factor and determine the effect of percent and depth of reinforcement, the density of the soil skeleton, download mode of bases on bearing capacity and deformability of weak clay bases; industry - construction.
