某大型工程结构加固方案的优选及施工

The Optimal Plan for Structural Reinforcement and Construction in a Big Engineering Project

在工程主体完工后,随着业主对建筑使用功能要求的改变,使得原有结构的荷载发生了变化,可能会造成原有结构将不能满足现有的荷载要求,这就需要采取一定的措施对原有结构进行加固补强,以确保该结构的稳定性及安全性满足要求.结合某工程实例,并通过比较几种加固方法的优缺点,选定碳纤维布加固为最优方案.同时,介绍了该工程采用碳纤维布进行梁板加固的施工过程.

After the completion of the engineering main body, with the alteration of architectural function requested by the owner, the load of intrinsic structure has been changed, which enables the original structure impossible to satisfy the load demand of existing function for intrinsic structure. So it is very essential for us to take some measures to strengthen the intrinsic structure so as to ensure the stabilization and security of structure. Taking a big engineering as an example, through the comparison and a- nalysis of the advantage; and disadvantages of several kinds of reinforcement methods, this article selects carbon fiber cloth reinforcement as an optimal plan, and in conclusion, it introduces the constructing process of girder and board strengthened by carbon fiber cloth.
