缓粘结预应力混凝土技术研究

The research on the bond-retarded prestressed concrete technology

分别介绍了传统后张预应力混凝土结构和缓粘结预应力体系的特点,阐述了缓粘结预应力钢绞线的研制及生产工艺,通过对缓粘结预应力梁进行荷载试验并与无粘结预应力梁作对比分析,验证了缓粘结预应力构件的优越性。

This paper introduces the characters of the traditional posttensionecl prestressed concrete structure and bond-retarded prestressed system. It has a exposition for the research and production technology on the bond-retarded prestressed strand. Through the comparison and analysis on the load research of the bond-retarded prestressed beam and unbonded prestressed beam, it demonstrates the advantage of the bondedretarded prestressed component.
