INTERACTION BETWEEN LONG PILES AND THE SOIL BODY EXPOSED TO NON-LINEAR DEFORMATIONS
Pages 22 - 27
Theoretical and numeral solutions to the problem of interaction between a long pile and the heterogeneous soil body are considered in the article. It has been discovered that the distribution of stresses between bottom and side sections of a pile depends on elastic and plastic properties of soils and the pile length-to-diameter ratio. Optimal geometric parameters of a pile can be derived by means of the optimal stress distribution between side and bottom sections of a pile.
The problem of interaction between a long pile and the soil body (the half-space) may be reduced to the problem of interaction between the soil body and the cylinder that has limited dimensions, namely, the diameter of and the height of where is the length of a pile. Solution to the problem in question (section 3) was also obtained through the employment of the method of finite elements (FEM) implemented in the Plaxis-2D software in the elastic and plastic environment. The graphic representation of the solution is provided in Figure 3. As expected, the results generated by analytical and numerical methods are similar both in terms of pile settlement, and in terms of stresses below the bottom end of a pile.
