Parameter Identification of Long-span Continuous Bridge Based on Canonical Correlation Analysis and GRNN

The method of parameter identification of long-span continuous bridge is established, which is based on canonical correlation analysis and GRNN theory. The parameter identification method is applied in a long-span continuous bridge construction control. Canonical correlation analysis result shows the key design parameters, which are close to the bridge construction linear and stress. With actual construction parameter error simulation, The GRNN parameter identification arithmetic computed result proves the method is feasibility. The parameter identification provides the bridge construction control certain technical support.
