Lian Huo Freeway In A Healthy State Of The Reinforced Concrete Bridge Static Load Test

Recently, study of bridge structure disease examination and structure damage evaluation become the focus in bridge area. Due to the design and construction originality error and the long influence of the environment to the structures, the reinforced concrete bridge structures always have some structure disease and damage. These structure disease and damage's happening and evolution will affect the structure capability and the normal use of the bridge structures in the service time. Especially, these structure disease and damage will affect the safety of the bridge structures. Scientific structure disease examination and structure damage identification to bridge and gaining actual structure work status of the bridge are precondition and foundation of right using.Through static load test research of bridge, understanding of its purpose on stress conditions and analysis for the bridge, the paper judges its safe reserve, provide necessary foundation for maintenance and strengthening according to monitoring and calculating result, it can both guarantee conditions of bridge's safe operation and save funds, in the meantime, it can provide maintenance and strengthening scheme and new structure design and calculation theory, as well as scientific foundation and reference value for evaluating the same old bridges in the future.
