Steel Tube Composite Column High Pier Continuous Rigid Frame Bridge Construction Risk Bigger Process Identification Study

The bridge construction of highway projects is an item of very complex system’s work, From preparation to completion of construction potential risks may occur.The basic characteristics of the bridge project is a huge investment, technical complexity, the project involves a wide range of engineering life cycle, Once the incident is significant, when compared with other production process of highway construction, with greater risk.The Main research contents of this article are:(1) Highway and bridge engineering construction method for steel pipe concrete composite column bridge piers.(2) Construction step analysis of concrete-filled steel tube composite column piers and importance analysis.(3) Laba pound bridge decks analysis of in-situ construction steps and the importance analysis.(4) Using MIDAS/CIVIL software, simulating the actual construction process carried out a computer analysis of the construction of the superstructure.Through research, The results help to improve the safety management system in highway bridge construction, formulate effective measures for dealing with risks of highway bridge, leap on similar projects, to improve the safety of highway bridges purposes.
