| Abstract: | Lanshu Bridge is the first curved single tower cable-stayed bridge in China.The tower bend toward the short span,and the stress status is complicated.The bridge was controlled by updated close-loop control method.By monitoring the stresses,displacements,cable forces and analyzing the errors,the control method played an important role in the construction safety and quality control.The method also provides a reference for the similar cable stayed bridges. |
