A New Monitoring Technology on Arch Bridge

In order to make the actual state of the bridge into the ideal state of maximum, we make real-time monitoring in the key parts of the bridge, and adjust to the design of the data to ensure the safety and reliability of arch bridge in the course of construction. Combined with the construction monitoring of the Sihe Bridge, this paper introduces the main bridge construction process on the large span tied arch bridge. Based on the construction monitoring of Sihe Bridge, this paper introduces the main contents and methods of monitoring point location, monitoring control of construction process, and discussed the construction monitoring technology of long-span X-style tied arch bridge.
