摘要
概述港口工程无粘结预应力连续梁的设计、施工及质量保证措施,特别提出预应力构件端部防腐保护措施。通过采用分段预制、分段张拉施工工艺,解决大跨度预应力混凝土连续结构的水上施工的技术难点;梁端部采用有粘结筋等防腐措施,确保端部结构安全。
This paper outlines the design,construction and quality assurance measures of the frame beams of the prestressed concrete with unbonded tendons in port engineering,especially the anti-corrosion measures for the ends of prestressed structure,deals with technical difficulties of water construction on large-span continuous prestressed concrete structure by the construction technology of sectional precasting and sectional tensioning.Anti-corrosion measures such as bonded tendons are used for guaranteeing the structural safety of the ends of beams.
