摘要
既有混凝土结构的加固改造是一个日益兴起的行业,可供选择的加固方法有很多种,如叠合混凝土法(加大截面法)、粘钢法、碳纤维加固法和体外预应力加固法等.确定合适的加固方法要综合考虑工程的实际使用环境和经济指标.针对某实际加固工程,计算并论证了叠合混凝土法在既有结构改变使用功能情况下进行加固的可行性和有效性,以期为类似加固工程提供参考.
Reinforcement and transformation of existed structure have developed rapidly. The reinforcement met- hods to be choosen include Superimposed concrete method （section enhanced method）, bonding steel method, CFRP strengthening and external prestressing method usually. The desirable strengthening way should take service condi- tion and project cost into account. Based on a reinforcement project,the paper calculates and demonstrates the feasibility and effectivity of superimposed concrete method when service function of existed structure is changed. The study result will provide valuable reference for reinforcement project.
