摘要
本文采用弹性力学及有限元方法 ,分析钢筋锈蚀产物体积膨胀在周围混凝土中的应力分布。提出了混凝土保护层四种破坏模式 :直角破坏、楔形破坏、垂直方向顺筋开裂及整层破坏。
Stress analysis in concrete due to corrosion of reinforcement is carried out,based on elastic mechanics and finite element method,Four models for pattern of concrete cover failure corner spalling,wedge spalling,vertical cracking and splitting spalling,are presented.Between results of investigation of corrosion damage in reinforced concrete structure and four models presented in the paper are agreement.
