混凝土增大截面加固法在某工程改造中的运用

The application of concrete increasedcross-section reinforcement method in renovation

随着时间的推移,混凝土结构因为种种原因会发生严重损坏,造成建筑物寿命的隧道,为了改变这一现状,对混凝土结构进行加固改造成为必然。探讨了混凝土结构加固的几种方法,着重介绍了增大截面加固法的原理及设计要求,并结合实际工程实例,将该加固法与其他几种加固方法进行了对比分析,结果表明,该加固法施工过程相对简便,成本较低,对原有结构影响小,具有较好的应用前景。

With the passage of time,the concrete structures will suffer serious damage due to various reasons,resulting in a shortened lifespan of buildings,in order to change this situation,it is inevitable to reinforce and transform the concrete structures.This paper discussed several methods for strengthening concrete structures,emphatically introduced the principle and design requirements of increased cross-section reinforcement method,and combined with practical engineering cases,compared and analyzed this reinforcement method with other reinforcement methods.The results showed that the construction process of this reinforcement method was relatively simple,the cost was low,and the impact on the original structure was small,which had good application prospects.
