广州华立科技职业学院 毕业设计（论文） 题目： 浅谈混凝土结构加固方法与技术 学生姓名： 朱梓华 学 号： 5420111044 专 业： 建筑设计技术 指导老师姓名： 谭带珍 论文提交时间： 2009年4月15日  中文摘要与关键词 我国是一个发展中国家，在过去的50多年间,我国的土木工程建设一直没有过,并且发展很快,愈来愈多的建筑物和构筑物已进入或即将进入老龄化阶段,修复加固在建筑业中的比重逐年增加,己有建筑物常常因设计或施工的缺陷以及长期使用过程中的老化、破坏,甚至自然灾害,造成混凝土结构承载力不足、开裂以及抗震性能不良等,影响建筑物的安全和使用功能,从而不得不考虑结构的修复加固问题。预应力加固法增大截面加固法外包钢加固法外部粘钢加固法增设支点加固法化学灌浆补强法水泥压浆补强法喷射混凝土补强法粘贴纤维材料加固法化学植筋Chinese abstract and keywordsChina is a developing country, in 50 years of in the past, civil engineering construction in our country has not stopped, and develop very fast, more and more buildings and structures have entered or will enter the aging stage, repair and reinforcement in the construction industry has been increasing year by year, buildings, often because of aging defects in design or construction as well as the long-term use of the process failure, even the natural disasters, resulting in concrete structure bearing capacity, crack and poor seismic performance, affect the safety of the building and the use function, thus had to consider the reinforcement structure repair. To solve these problems will greatly enhance the performance and service life of concrete structure, expand the development prospects of concrete structure.This article from the history of the development of concrete structure, concrete basic concept, types, characteristics, characteristics and application scope and application status of the technology of strengthening concrete structures, main research; analysis of concrete structure strengthening method, mainly including prestressed reinforcement, increase cross-section reinforcement method, wrapped steel strengthening method, the external bonded steel reinforcement method, reinforcement method, fulcrum chemical grouting reinforcement method, cement grouting reinforcement method, method of reinforcement, concrete spraying fiber paste reinforcement me
