3、ges in our country both in construction and in technology have made great achievement, on the various types of bridge are of typical bridge has been built in our country, and has the world's leading achievements in s

4、ome areas, the bridge construction of our country to some extent represents the world bridge technology development direction. Running of the bridge construction in China with the goal of building a high standard, high s

5、tarting point, believe that these will be to a higher level of bridge construction in our country. Here for x river hydrological conditions and the actual requirements of highway design, according to relevant national la

6、ws and regulations, for the design. This design for mainly for the following three aspects, first is the calculation of hydrology section, it is in view of the existing data, determination of bridge length, drilled pile

7、of pile length, the determination of bridge deck elevation, etc, this part is the foundation; And then calculate the net long of the bridge, through scheme comparison choose the appropriate form of bridge and bridge sect

8、ion, entering into the upper structure calculation, here is the most core, the design not only on the longest, is more of a bridge for the overall performance is important, including load calculation, prestressed reinfor

9、ced the construction of prestressed loss of prestress, beam calculation and deformation calculation, local anchorage calculation, horizontal isolation beam, driving but as well as the calculation of the usage of these ar

10、e affect the bridge important calculation, checking calculation of link, the bridge of good driving conditions and good quality are controlled by these calculations; Finally, start the calculation of bottom structure, in

11、frastructure is to the upper structure load transfer to the foundation, and resist the role of adverse external conditions, these is a function of the lower structure, it mainly manifests the calculation on cap beam, pie

12、r column and pile foundation, the selected here for the single row, double column bored pile foundation, the calculation of the selection for the calculation of bridge piers. Bridge as a whole, each part is crucial for t
