| Abstract: | The accuracy of the construction of high-speed railway bridges with ballastless tracks is very demanding.The mechanical performance of the PC continuous curved beam bridges that are built by cantilever construction is analyzed first in the paper,with the main construction control contents for this type of bridge and calculation formulae for themolding board level and horizontal coordinates subsequently put forward.With the Weihe Mega Bridge of the Zhengzhou-Xi＇an Passengers-oriented Railway as a practical example,the feasibility of the high-precision construction control is tested. |
