Mechanics Model of Stress Compute on Contract Deformation of the Concrete’s Foundation Mat
It is a knotty problem in the actual project, that contraction deformation produce stretching stress on the concrete engineering. To counter deformation characteristic of the large-scale concrete foundation mat in construction temperature field,this paper has put a complete set of compute mechanics model of stress analysis and influence limits of constrained deformation on the basis of Saint-Venant’s principle. A number of computing formulas were inferred with theory of materil mechanics and structural mechanics,so that have obtained a set of analysis methods.By theory analysing and computing an actual project, it was that compute result accorded with structure law and the seat of compute crack was identical with cracking seat of the actual project.So, the achievement has the same values about the theory and the engineering application.
