損傷混凝土結(jié)構(gòu)加固性能及加固后耐久性研究
發(fā)布時(shí)間:2018-08-02 12:57
【摘要】:混凝土誕生的一個(gè)多世紀(jì)以來(lái),由于老化、環(huán)境侵蝕、自然災(zāi)害、人為因素的影響,混凝土構(gòu)件存在著普遍的損傷問題。因此混凝土的發(fā)展史也是損傷混凝土的加固史,混凝土加固技術(shù)貫穿了混凝土發(fā)展的始終。但是在混凝土加固活動(dòng)中加固主體一般比較重視加固后的混凝土結(jié)構(gòu)強(qiáng)度,對(duì)混凝土結(jié)構(gòu)加固以后的整體耐久性并不重視,這種現(xiàn)象讓加固活動(dòng)本身的積極意義大幅度削弱。針對(duì)這一現(xiàn)象,本文從混凝土結(jié)構(gòu)加固性能和耐久性能出發(fā),結(jié)合損傷混凝土加固和加固后的耐久性實(shí)際,對(duì)損傷混凝土結(jié)構(gòu)加固性能及加固后耐久性進(jìn)行簡(jiǎn)要分析。
[Abstract]:Since the birth of concrete for more than a century, due to aging, environmental erosion, natural disasters, human factors, there are widespread damage problems of concrete members. Therefore, the history of concrete development is also the history of damage concrete reinforcement, concrete reinforcement technology throughout the development of concrete. However, in the concrete strengthening activities, the main body generally pays more attention to the strength of the reinforced concrete structure, and does not attach importance to the overall durability of the reinforced concrete structure, which greatly weakens the positive significance of the strengthening activity itself. In view of this phenomenon, this paper analyzes the strengthening performance and durability of damaged concrete structures from the point of view of strengthening performance and durability of concrete structures, combining with the actual durability of damaged concrete structures after strengthening and strengthening.
