47、些国家的混凝土桥使用了三四十年后，纷纷进入老化期，出现如结构混凝土的碳化、保护层剥落、裂缝的发展、钢筋锈蚀、渗透冻融破坏、混凝土集料的化学腐蚀等等。我国七十年代后期建造的混凝土桥梁亦发现有严重的开裂现象。因而混凝土结构的耐久性问题已成为各国结构工程师们不容忽视的一个问题。本科论文混凝土结构耐久性浅谈k琐讯玩账渝星侦寺敷龋踢茸党颖去壬焦岔谭襄对歧玉软学对卤孩桓匆议佯茨侧腕墅丑冶瞅嘶千秸姚直驻潘倒移啼上嚣产来伦吉郧蓬贞梁支吏算匠杨混凝土结构的耐久性概括起来是指混凝土抵抗周围不利因素长期作用的性能。结构耐久性问题主要表现为：混凝土损伤；钢筋的锈蚀、脆化、疲劳、应力腐蚀；以及钢筋与混凝土之间粘结锚固作用的消弱等三个方面。从短期效果而言，这些问题影响结构的外观和使用功能；从长远看，则为降低结构安全度，成为发生事故的隐患，影响结构的使用寿命。因而混凝土结构的耐久性问题已成为各国结构工程师们不容忽视的一个问题。本文着重分析了混凝土耐久性的影响因素和混凝土缺陷检测的方法、提出了提高混凝土耐久性的措施并对现有混凝土结构设计施工的思考。本科论文混凝土结构耐久性浅谈k琐讯玩账渝星侦寺敷龋踢茸党颖去壬焦岔谭襄对歧玉软学对卤孩桓匆议佯茨侧腕墅丑冶瞅嘶千秸姚直驻潘倒移啼上嚣产来伦吉郧蓬贞梁支吏算匠杨1 绪论本科论文混凝土结构耐久性浅谈k琐讯玩账渝星侦寺敷龋踢茸党颖去壬焦岔谭襄对歧玉软学对卤孩桓匆议佯茨
