摘要:
已有工程检测、理论分析和试验研究表明:风对混凝土碳化的加速作用是客观存在的,风对混凝土碳化的影响会使混凝土结构截面提前发生破坏.为使混凝土结构各截面耐久性一致,对该问题进行深入研究很有必要.基于试验与实测数据以及有限元软件FLUENT的分析,对风压作用下混凝土箱梁结构截面等耐久性设计提出了建议,同时,也为混凝土结构等耐久性设计理论的建立做了初步探索.通过构造简单的算例显示,对混凝土结构截面进行等耐久性设计时,将风对混凝土碳化的影响这一因素考虑在内会使设计更加科学合理,能够有效延长桥梁结构的使用寿命,并对指导实际混凝土工程设计、施工和维护具有重要的应用价值.
Abstract:
The existing engineering tests, theoretical analysis and experimental studies show that the acceleration effect of wind on concrete carbonization is objective, so the section of concrete structure will be damaged in advance. In order to make the durability of each section of concrete structure consistent, it is very necessary to study this problem. Based on the test and measured data and the analysis of the finite element software FLUENT, in this paper, some opinions on the equal durability design of concrete box girder structure section under the influence of wind pressure are put forward. At the same time, it also makes a preliminary work for the establishment of equal durability design theory of concrete structure. In the design process, consideration of the influence of wind pressure on concrete carbonization can make the equal durability design of concrete structure section more scientific and reasonable by means of simple calculation example. The method can effectively extend the service life of the bridge structure, which has important application value for guiding the design, construction and maintenance of practical concrete engineering.
