| 摘 要： | 在自密实混凝土与老混凝土约束收缩试验的基础上,本文采用大型有限元软件ABAQUS进行了新老混凝土粘结的约束收缩模拟,并与试验结果进行比较,以验证有限元模型的可行性。同时从应力分析的角度研究在约束收缩的作用下,新老混凝土粘结的应力分布规律,考察新混凝土强度对约束收缩的影响,为采用自密实混凝土作为新混凝土进行结构的加固设计提供一定的参考依据。

| Abstract: | Based on the test results of adherence of self-compacting concrete to old concrete,the restrained shrinkage of adhesion between new and old concrete is simulated by finite element program ABAQUS.Compared with the test results,the finite element model is proved to be effective.The stress distribution law of adherence of new on old concrete under restrained shrinkage is studied from stress analysis.It can be taken as a reference for the design of strengthening of concrete structure with self-compacting concrete as new concrete. |
