BRIDGE RISK ASSESSMENT STUDY BASED ON NEW STRUCTURE DESIGN IDEA

Safety and durability of bridge is very important for bridge structures. It is necessary to construct the new structure design idea and reduce the risk assessment to protect the safety and durability of bridge. The bridge risk assessment based on the new structure design idea for durability are investigated, the characteristics and accident reasons are analyzed. A new structure design idea considering the safety and durability of bridge in life cycle is proposed. The theory and practice of bridge risk assessment are studied. The assessment standards in design stage are put forward. Finally, an assessment system of bridge safety and durability is established.
