| Abstract: | The relation between displacement of prototype and that of model if derived for the linear elastic body at its body force condition of self-weight based on the similarity theory.Accodding to the results of discussion of the equation representing the relation and analyse of a pillar body self weight compression, the nonlinear relation between displacement and size is obtained. |
