Construction Control of a Continuous Beam Arch Composite Bridge
The geometric shape and internal forces were monitored during the construction of the hypostatic framework structure which is a composite system of steel beam and arch. The displace settlement was measured for the control of the geometric shape. And nine vibrating wire strain gauges were embedded on the key sections for the real time control of internal force. In order to cancel out the interference of the temperature variation effectively, displace settlement and internal forces were monitored around the clock at different time points. Then the measured values were compared with the theoretical values. Based on the measurement of temperature variation and strain, the settlement during the process of frame construction can be surely ascribed to thermal stress in the high redundancy structure. It should pay close attention to the changes in the future similar steel Beam Arch Composite Bridge construction and monitoring system.
