Mathematical Model of Displacement Distribution for Safely Monitoring of Concrete Dams

In this paper, mathematical analysis and dam theory are applied to the study of the model of displacement distribution. The mathematic formula of the relationship between the displacement and the load has been obtained by combining the deformations with the coordinates of the points. In the light of the prototype observation data of a project, the method for establishing the distribution model is introduced. Each component is mathematically expressed and the deterministic model and hybrid model of the deflection curve are set up. The regression results show that the computational results are in good agreement with observation data and the precision is satisfactory.
