鉸接空心板簡支梁橋加固維修方法的研究與實踐
[Abstract]:With the continuous development of the economy, the bridge undertakings in China have made great progress. The precast hollow slab bridge has been widely used in the small and medium span bridges because of its simple technology, small construction difficulty and low cost. A large number of engineering practices have shown that the structure characteristics and construction technology of the hollow slab bridge have also caused various diseases. It has a serious influence on the bearing capacity and durability of the bridge. Therefore, it is very important to study the mechanism of the disease and to discuss the reinforcement and maintenance methods for different types of diseases. The following research work is carried out on the reinforcement maintenance project of the bridge: the hollow slab beam bridge. The overall stress, the common disease, the cause of the disease, the classification of the disease degree and the reinforcement and maintenance method are analyzed and summarized. The bridge technical condition is evaluated through the conventional test, the static load test and the dynamic load test. In view of the actual situation of the bridge disease, the reinforcement and maintenance scheme of the bridge is designed, and the calculation analysis and the analysis are made. The effectiveness of bridge reinforcement is verified by the completion test.
