Krysan V. The peculiarities of elastic and rheological properties of soils determination.

The object of study - the process of sealing with the rheological properties of water-saturated soil. The aim of the thesis is to develop methods for determining the elastic and rheological properties with the property that creep of water-saturated soil. Research methods: Theoretical and practical results: the analytical solution of the problem of the change of the stress - strain state under compression compression of the soil sample during the test torque method; analytic solution of the problem of the indentation of an absolutely rigid punch in having the property of creep of saturated half-space; the analysis of the fundamental relations of the theory of creep S. C. Vjalova; in the model of the elastic water-saturated, having the property of creep, the Foundation of the analysis of the curves of sediment - time" for under compression compression of a soil sample. The technique of extrapolation of creep in the region far. According to his idea, it is close to the method of L. T. Roman, and B. Shapoval, graphic-analytical empirical methods. The main difference of the proposed method of extrapolation is: clear physical justification; the possibility of automating the process of extrapolation; the use of methods of mathematical statistics for the implementation of the extrapolation process; similar studies performed for die testing. Scientific novelty: improved equipment, which allows to test a torque method soil samples under compressive compression, to determine their deformation and rheological properties; received a new analytical solution of the problem of stress - strain state of soil sample with the property of creep under conditions of compression of the compression torque method; continued development of fundamental ratios S. C. Vjalova, developed a method of extrapolation of creep of soil samples; received further development of the analytical solution of the problem of indentation of a rigid punch, wet basis; the solution used in the method of determining the elastic, filtration and rheological characteristics of water-saturated soil foundations; improved methods of determining the elastic, filtration and rheological characteristics of the water-saturated soil on the basis of the analysis of the results of laboratory tests with constant load. Degree of implementation: in the implementation of research results in the practice of engineering LLC "EKFA" ( Poltava) calculated sediment reinforced rigid elements of the bases granaries. In addition, in SE "Dneproggitiz implemented method of rapid determination of deformation and rheological characteristics of clay soils. Purview: building.
