The equations of motion are established referring to the current-unstressed configuration,by which the coupling between axial forces and bending moments is naturally considered without introducing geometric stiffness matrix.

Assembled geometry and unstrained geometry of super long span cable-stayed bridges;

Taking the construction control project of Yangtze River Highway Bridge from Suzhou to Nantong as an example,the model of entire bridge is established to simulate the whole construction process in terms of basical ideal of geometry construction control method,and then the unstressed configuration of steel box girder and unstressed cable length in the service stage are found out.

The article attempts to find some practical solutions by researching the current situation of China s tourist industry.
