In recent years, rotation construction is widely used in construction of arch birdge, and the method of construction is difficult and has complicated process. Construction process control for rotation construction of the long-span anch bridge is not only the key measure to ensure the states meeting the design requirements of the constructed bridge, but also is the important part to ensure the construction quality and safety. Therefore, it is necessary to control the construction for the long-span self-anchored arch bridge. The paper established the control system according to the rotation constrcution for the long-span self-anchored arch bridge which is overpass a exited major highway. And took a follow-up observations for the actual states of the constructing arch bridge, and used the finite enlement software ANSYS to analyze the stress of the structure and static and dynamic stress in the process of rotation construction. Comparing the theoretical value to the measured results showed that there was good meet between the results. And the rotation construction was stable, the vertical displacement and the acceleration were smaller, and didn’t take a bad effects on the structure. According to the results of the finite element and monitoring, it will provide the target of the construction monitoring for each construction segment, and meet the final design of the bridge, furthermore it will provide a reliable reference for the smooth progress of construction.

The long-span spatial steel structure takes its complex construction process because of its features, such as large scale, wide range, and long cycle duration. Simultaneously, the structural construction process can not only affect the shaping of long-span spatial structure, but also produce a great effect to structural final force state, which makes the construction monitoring of long-span spatial steel structure necessary. The most important construction parts for Shenzhen Bay Stadium steel roof are unloading process and closure process. Considering the structure complexity in the construction phase, a structural health monitoring system was installed, which began to be built in early 2010 and contained two phases: construction monitoring and operation monitoring. In this paper, the temperatures and displacements monitoring in construction phase are firstly described in detail. The monitoring data of temperature and displacement measured in unloading and closure phases are then analyzed, respectively. According to these monitoring data, the comprehensive understanding for the structural performances in construction phase is shown and discussed, which can provide a reference of construction monitoring for the related projects.

In order to control the tower deviation in the cable hoisting process of long-span concrete-filled steel tubular arch bridge during construction monitoring, a practical method of tower deviation correction was studied and established. In the paper, based on the studies about the deviation error formation mechanism of tower in the process of cable lifting, the relevant formulas of the arch rib elevation changes caused by the change of tower state were deduced. The traditional control methods including increase of tower stiffness and strength of the anchor cable, are not effective, costly, and require a longer construction period. To overcome these defects, in virtue of the Beidou GNSS measurement system and hydraulic jack active control system, the active control technology of the CFST (Concrete Filled Steel Tube) arch bridge tower deviation was thoroughly studied. Besides, a perfect active control theory was established. Finally, the author puts forward the idea of reverse pulling tower deviation. The field measurement and comparative study show that after the optimization of this method, the tower deviation is within 2 cm, and the error meets the specification requirements. The proposed method can accurately control the tower deviation in the process of arch bridge cable hoisting, and establish a set of perfect active control related systems and theories, which is especially suitable for the construction monitoring and adjustment in the construction stage of arch bridge, and can provide reference for the construction control of tower deviation of the same type of bridge.
