摘要
在我国建筑领域中,预应力钢筒混凝土管(PCCP)的应用接近30年,而在一些早期工程中应用的PCCP出现了不同程度的老化和损坏,从保证其性能和安全的角度,需要做好相应的结构性修复更新。论文结合PCCP的特点,就几种在发达国家比较常见的PCCP结构性修复更新技术进行了分析,希望能为相关技术在我国的应用实践提供参考和借鉴。
In China’s construction field,prestressed concrete filled steel tube(PCCP)has been used for nearly 30 years,but PCCP used in some early projects has experienced different degrees of aging and damage.From the perspective of ensuring its performance and safety,it is necessary to repair and update the corresponding structure.Combined with the characteristics of PCCP,this paper analyzes several common structural repair and update technologies of PCCP in developed countries,hoping to provide reference for the application practice of related technologies in China.
