| Abstract: | Crack breaking may be induced by thermal stress after arch sealing for grouting of arch dam. The variable dimension fractals of prediction model about the temperature rise after sealing arch is established through data processing analysis. And then each fractal dimension is calculated to fit the predicted value. With the example of Tiantangshan arch dam temperature monitoring during the construction to analyze and forecast. The result shows that the variable dimension fractals model takes advantage of the self-similarity feature,can be well applied to predict arch dam monitoring data,and accuracy can meet the requirements of engineering. |
