Stress theory of nonlinear elastic plastic viscous interaction of the loaded single pile with base soil

The need of development of the uniform theory of non-linear elastic plastic viscous deforming of fully-stressed dispersive soil for the base of the loaded single piles is shown. The model for the force interaction of the single loaded pile with surrounding soil of the base is developed. The features of the internal soil friction angle and the deviation angle of the resultant stress components from the vector of the extremely principal compression stress to the plane of a sliding site are revealed. The theoretical justification of a physical, mechanical and mathematical entity of an angle of internal friction of the soil is made. The theory of the development of the states of limit equilibrium in the processes of interaction of the loaded single piles with soil of the base is given as a part of the provisions of a scientific subject to the stress theory of elastic plastic viscosity of five states of limit equilibrium, initial elasticity and structural durability of soil. The conclusions on the content of the results of scientific development are given.
