Abstrait:

In order to ensure the safe implementation of walking-type incremental launching steel box girder. Taking a simply supported wide steel box girder bridge as an example, this paper analyzes the local stress of the wide steel box girder with four supporting points of walking pusher, and quantitatively determines the three single parameter related control thresholds of lateral deflection, longitudinal pusher asynchrony and vertical lifting asynchrony that are concerned in the construction. Based on the single parameter control research, the two parameters dynamic control threshold range is proposed. The calculation results show that two parameters analysis provides a more reliable means for walking-type incremental launching construction and is a necessary supplement to the conventional single parameter control.
