Application of Information Construction in Highway Tunnel

The practical application of basic principles of information construction in highway tunnel was introduced in this paper. An information construction model of highway tunnel was established by accessing to site data and inversing the surrounding rock parameters and optimizing the construction parameters and so on. The predictive deformation and parameters inversion of surrounding rock construction were analyzed in actual highway tunnel with the construction model. Predictive deformation values of the surrounding rock and the actual measurements values were compared, and the predictive deformation values were in good agreement with the measured values. There was a generally law that the predictive values were less than the measured values. Finally the causes of error were analyzed in the paper.
