Popis: | Introduction. When the footing is embedded in loose clayey soils, buildings may settle down for a long period of time. The projected settlement period is of great importance for the design of foundations designated for such soils. Therefore, the approach to describing the process of foundation settlement must be considered as rheological. This article addresses the setting of and a solution to the problem of interaction between a long pile and surrounding multilayered and underlying soils with account taken of the rheological properties of the surrounding soil body. The creep process is considered with account taken of stabilization. Materials and methods. Linear problem setting is considered. The analytical method is employed to present a solution. The rheological stabilization parameter is used to describe the creep process. Results. An expression is derived to determine the reduced shear modulus for the multilayered soil body. The relationship between the value of the force applied to the pile toe and the time is derived with regard for the rheological stabilization parameter. Analytical solutions are enforced by graphs in the article. Graphs describing the relationship between pile settlement, the force applied to the toe of the pile, passing through alternating soil layers, and the time are provided for various values of viscosity and the variable parameter of stabilization. Conclusion. Solutions, obtained by the co-authors, are used to perform the preliminary identification of displacement of long piles and surrounding multilayered underlying soils. The rate of stress changing underneath the pile toe depends on soil viscosity. The rheological coefficient of stabilization has a major effect on the time of pressure stabilization underneath the pile toe, as well as the time of the pile settlement stabilization. Dependencies, derived in this article, make it possible to project the future settlement pattern. |
