Mexico × o. 8 + o. 1 = i × o. 8 + o. 1 (where i = l, 2, j = l, 2,3),mbt calzature uomo, the results shown in Table 4.

Use of such methods of observation points PL15401 intelligent back analysis, we can see the dam concrete elastic modulus E. = 28.96GPa, the bedrock of the elastic modulus E2 = 27.04GPa. Table 5 Network operating results Table5: Resultofnetworkingrun network input network output 88 known 8E1E2O. 1O. 3784450.192580.8868O. 7O224 Conclusion In this paper,UGG Schuhe, intelligent back analysis has been Geheyan concrete dam body and the elastic modulus of the bedrock, to a certain extent, reflect the physical parameters of concrete and rock. The method of evaluating the strength and stability of the dam, the dam operating conditions control, testing the correctness of the design to ensure the safe operation of the dam provides a reliable analysis of data, is of great significance. ■ |
