PCCP破坏机理及其加固现状

Failure mechanism and reinforcement status of prestressed concrete cylinder pipe

PCCP在使用过程中会出现裂缝、断丝等劣化现象,甚至出现爆管。开展PCCP破坏机理及其加固技术的研究,对于指导工程实践、保障工程安全具有重要的学术价值和经济意义。通过对国内外文献分析与研究,依次阐述了PCCP破坏机理和加固的研究进展情况,并结合目前研究状况对进一步的研究重点和方向进行了探讨。

During the use of Prestressed Concrete Cylinder Pipe( PCCP),cracks,broken wires and other deterioration phenomena may occur,and even a tube may burst. The research on the mechanism of PCCP failure and its reinforcement technology has important academic and economic significance for guiding engineering practice and ensuring engineering safety. Through the analysis and research of domestic and foreign literatures,the article expounds the research progress of PCCP’s failure mechanism and reinforcement,and discusses the further research focus and direction based on the current research situation.
