| Abstract: | According to the alignment adjustment about rib-assembling coursing of Long-span CFST arch bridge, the basic equations for alignment adjustment are deduced using the least square method. A method of adopting changeable initial length unit that is applied to imitate adjust cable is put forward. As the engineer example proved that the method is true and practical. |
