Application of new materials developed by the project in a large bridge
Project Introduction: The project carried out a series of theoretical and technical studies on the durability and safe service of concrete structures such as Bridges and docks in typical sub-tropical service environment, and achieved the following innovative results: 1) Invented a variety of advanced new building materials such as fiber reinforced laminate, established the environmental fatigue and fracture theory of advanced materials reinforced concrete structures, and established its environmental fatigue/durability evaluation method and technology; 2) Invented a series of (prestressed) fiber reinforced RC structure technology, and established the life extension and durability technology of fiber reinforced/strengthened RC structure under service environment; 3) Established the life extension and durability technology of steel fiber polymer structure concrete composite structure, formulated the construction technology and obtained the provincial construction method. The project has obtained 23 authorized invention patents and 25 other intellectual property rights. The research results have been applied to the life extension reinforcement of 34 Bridges, 6 roads and 3 docks, and achieved significant social and economic benefits.
