摘 要

在長期的自然的環(huán)境下使用環(huán)境的功能結(jié)構(gòu)，其功能減弱不可避免地漸漸地，我們的結(jié)構(gòu)工程的責(zé)任不只是必須完成建設(shè)前期項目工作，但必須能夠科學(xué)評價結(jié)構(gòu)的破壞目標(biāo)法律和程度，并采用有效的方法保證結(jié)構(gòu)的安全使用，該結(jié)構(gòu)加固將成為一個重要的工作。什么可以預(yù)見將是21世紀(jì)，人類建筑的混凝土結(jié)構(gòu)，鋼結(jié)構(gòu)，砌體式結(jié)構(gòu)等為主另外，現(xiàn)階段我會覺得在結(jié)構(gòu)加固我們這方面的研究也應(yīng)借此作為主要的突破方向。

Abstract：structure in the long-term natural environment and under the use environment's function, its function is weaken inevitably gradually, our structural engineering's duty not just must finish the building earlier period the project work, but must be able the science appraisal structure damage objective law and the degree, and adopts the effective method guarantee structure the security use, that the structure reinforcement will become an important work. What may foresee will be the 21st century, the human building also by the concrete structure, the steel structure, the bricking-up structure and so on primarily, the present stage I will think us in the structure reinforcement this aspect research should also take this as the main breakthrough direction.
Key word： Concrete structure reinforcement bricking-up structure reinforcement steel structure reinforcement
1 Concrete structure reinforcement
Concrete structure's reinforcement divides into the direct reinforcement and reinforces two kinds indirectly, when the design may act according to the actual condition and the operation requirements choice being suitable method and the necessary technology.
1.1 the direct reinforcement's general method
1.1.1 Enlarges the section reinforcement law
Adds the concretes cast-in-place level in the reinforced concrete member in bending compression zone, may increase the section effective height, the expansion cross sectional area, thus enhances the component right section anti-curved, the oblique section anti-cuts ability and the section rigidity, plays the reinforcement reinforcement the role.
In the suitable muscle scope, the concretes change curved the component right section supporting capacity increase along with the area of reinforcement and the intensity enhance. In the original component right section ratio of reinforcement not too high situation, increases the main reinforcement area to be possible to propose the plateau component right section anti-curved supporting capacity effectively. Is pulled in the section the area to add the cast-in-place concrete jacket to increase the component section, through new Canada partial and original component joint work,
