| Abstract: | The lengthways moving course of the bridge building machine is studied in the paper,and the spots on the leading beam to be tested is fixed according to the actual structure and the analysis of the stress state. Through on-the-spot test, the stress law on the leading beam of bridge building machine during the lengthways moving is studied. The results can be referenced for the design and operation of the bridge building machine. |
