Discussion on the management of bridge prestressing tension construction
桥梁预应力张拉施工管理问题探讨

摘要

预应力张拉施工是桥梁结构成型与质量控制的关键环节，其管理水平直接关系受力体系的可靠性与耐久性。当前现场施工中常见张拉力偏差控制不足、设备校准不规范、张拉同步性难以保证等问题，易导致预应力度不足或超张拉，进而影响结构安全储备。基于工程实践，围绕张拉参数控制、过程监测与质量追溯等核心管理要点展开探讨，分析问题成因并提出改进路径。通过构建可量化的张拉控制体系、强化设备状态管理和现场工序衔接，可有效提升张拉精度与施工可控性，为桥梁施工质量提供可靠保障。

Abstract

Prestressed tensioning construction serves as a critical phase in bridge structural formation and quality control, where management standards directly determine the reliability and durability of load-bearing systems. Current field practices often face challenges such as insufficient tension deviation control, non-standard equipment calibration, and difficulties in ensuring synchronization during tensioning operations. These issues may result in inadequate prestress levels or over-tensioning, thereby compromising structural safety reserves. Drawing from engineering practices, this study examines core management aspects including tension parameter control, process monitoring, and quality traceability. By analyzing root causes and proposing improvement strategies, the research demonstrates that establishing quantifiable tension control systems and enhancing equipment condition management with optimized on-site workflow coordination can effectively improve tensioning accuracy and construction controllability, ultimately providing reliable quality assurance for bridge construction.
