Study on Construction Monitoring Technique of Long-span Steel Truss Bridge

Sun Buqin;Ai Zubin;Hou Shengjun;  
Taking a long-span steel structural pedestrian overpass as the practical example, the article introduces the technological gist and implementation method of the monitoring of bridge assemble construction and unloading construction stage after completion in detail. The large-sized finite element software ABAQUS is used to simulate and calculate the deformation of bridge. The control of pouring process and the adjustment of structural elevation during construction can achieve the pre-designed stress state and geometric alignment. The bridge structure is monitored in real time during the construction. The monitoring result can correct the control parameters of construction process. After the result of calculation model is correspond to the practical monitoring result, the calculation model can be used to guide the following construction. The relative experience can be referred for the construction monitoring of the similar projects.
