| Abstract: | The creep of concrete will cause arch of simple supported railway bridge. Value of creep arch of prestressed beam is monitored by dynamic control technology of roadbed settlement to find out the changing rule and predict ultimate value of creep arch of bridge. The data accumulated in the process of monitoring can provide reference for future construction of engineering. |
