| Abstract: | Horizontal preframe method was adopted when steel stiffening girders of Xihoumen Bridge were fabricated, i.e. the steel box girders were pre-assembled in horizontal direction. To insure the vertical line figure of girder segments is right, relevant parameters should be calculated and stimulated first according to design data, then every part of the steel box should be adjusted in preframe process, and finally the linear accuracy should be checked. |

| Keywords: | horizontal preframe vertical line figure calculate adjust check |
