Safety And Risk Assessment For Long-span Continuous Rigid-frame Bridges During Design Stage

Bridge in the construction process there will be numerous risks influence the safety performance.Therefore,this paper taking a bridge as depends on the project,which based on risk characteristics of the bridge may exist in the design stage.From the sources of risk analysis,risk assessment and response measures three aspects.The major research contents of this paper are as follows:1?In order to understand the current situation of domestic and foreign risk research,analyze the common risk sources of bridge design and analysis methods;2?Based on a bridge,this paper introduces the construction condition of the bridge,analyzes the possible risk of the bridge from various aspects,and puts forward the corresponding measures to deal with the risk assessment of the bridge.On the basis of the actual engineering,engineering site investigation based on established risk assessment system for bridge engineering design stage,and formulate the corresponding risk control measures,has provided the reference for bridge engineering design and construction.
