摘要
阐述了如何对其预应力施工进行监控,总结了预应力施工过程中质量控制和技术要点,并介绍了预应力施工中如何正确估计预应力损失和准确计算钢束理论伸长量,以确保桥梁的预应力施工质量,提高预应力混凝土桥梁结构的耐久性。
This paper introduces monitoring methods for prestress construction as well as quality control and technical key points in construction. Ways how to correctly calculate the loss of prestress and theoretical extension value of reinforcement are also introduced in order to ensure prestress construction quality of bridge and improve durability of bridge with prestressed concrete structure.
