Research On Bridge Construction Risk Management Technologies Of Kai-Lan Steel Tube (CFST) Arch Bridge

After entering the new century,with the rapid development of city size and economic construction,people on the traffic demand more and more.Traffic has become an important part of economic development.Through the existing traffic line erecting new bridge is an effective way to improve the traffic of the CFST arch bridge with beautiful light,vertical stiffness,the upper structure light which many builders favored.Therefore,CFST arch bridge gradually become a hot spot of bridge construction.In this paper,based on risk management and safety management theory,combining the process and working procedure of the bridge construction,road construction across the G220 to Zheng Xu passenger line bridge construction as a background,optimization design of construction scheme of continuous arch bridge of concrete filled steel tube has been researched.The risk identification of security risks in the construction of CFST arch bridge,determined the risk factors of construction safety.And the third-party security risk assessment and evaluation used to the security risk of engineering construction management.Based on this,it ensured the safety of construction and the project construction period,economic and social benefits.
