| 摘 要： | 钢板-混凝土组合加固是一种基于钢-混凝土组合梁理论的新方法。介绍该方法在桥梁工程中的实际应用。实践证明,组合加固具有不降低原桥桥下净空高度、不要求原结构表面平整,可显著提高桥梁的承载力、刚度及防撞击能力等显著优点,为旧桥加固提供了新方法。

| Abstract: | The structural strengthening with steel plate and concrete composite is a new method based on the theories of steel and concrete composite girders.In this paper,the practical application of the method to the strengthening of reinforced concrete bridges is presented.Practice proves that the strengthening with the composite has obvious advantages of not reducing headroom under the original bridges and not requiring surface evenness of the structures.The composite can significantly improve the carrying capacity,rigidity and collision-proof capacity of the bridges and may contribute a new way to the strengthening of aged bridges. |
