Abstract:

Finite element method is employed to study the influence on silo foundation including different constitutive relations of elastic part of soil and the different ways of applying coal load. Based on this, the variations in following aspects are analyzed: coal pressure, contact pressure of pile-soil, internal force and deformation of pile and settlement of subsoil. According to the analysis, we will get the optimal design of silo foundation on the basis of the fact that the elastic modulus of soil improves with soil compaction, and coal, silo and subsoil interacts with each another to ensure the force status of silo foundation more practical.

Key words: way of applying coal load, porous elasticity, linear elasticity, elastoplasticity, finite element analysis
