Взаимодействие длинной сваи конечной жесткости с уширенной пятой и окружающего грунта

Abstract

The article is formulating and solving problems of the interaction of the long pile with finite stiffness with the broadening heel and the surrounding soil, having nonlinear and rheological properties. It is shown that the distribution of longitudinal stresses, in the trunk of the pile and tangential stresses at the contact with the soil pile depth is not linear, and this nonlinearity depends essentially on the nonlinear properties of the soil, the ratio of length and diameter of the pile and its stiffness. Judgments obtained in closed form allow us to determine sediment pile at the pile tip and heel as well as the voltage at the heel of the pile. We also consider the problem of interaction of long compressible piles surrounding soil within a contact weakened layer. To do this, enter the stiffness coefficient of the contact layer having a dimension of [kN / m3, t / m3], and to account for the viscosity of the soil layer is introduced factor having the dimension [kN / m3 ∙ s].
