| Abstract: | The construction control of continuous rigid frame bridges by the segmental cantilever method is studied in the light of engineering practice of Xiaoanxi bridge,and the feasible control methods are proposed.Furthermore,the influence of shrinkage and creep on the large-span bridge during its service is specially analyzed.An additional camber with shrinkage and creep is counted in.The better connecting precision is acquired,the smoother line-type of the bridge is formed. |

| Keywords: | continuous rigid frame construction control shrinkage and creep |
