Interaction of Gravel Piles with the Surrounding Soil and Raft

Аннотация

This paper provides a quantitative assessment of the stress-strain state of the "crushed stone pile−surrounding compacted soil−grillage" (cell) system under static and variable loads, taking into account the elastic and elastic-viscous properties of the pile and the surrounding soil. The potential for defining the parameters for deformability and viscosity of the cell, required for carrying out simplified calculations for the foundation known as "piles under the slab," is illustrated. The influence of the pile on the dynamic properties of the base (without piles), including the dynamic response factor, dependent on the frequency of the natural oscillations of the cell, with and without the influence of the pile, is evaluated.
