Abstract: The accuracy of stress–strain data in bridge construction monitoring directly affects the reliability of structural safety assessment. In response to the risk of data distortion, a full-chain error traceability model of "sensing layer–transmission layer–decision layer" is established to systematically analyze temperature drift, concrete shrinkage and creep effects, the mechanism of key error sources such as embedded strain gauge positioning deviation and early failure. The study used monitoring data from multiple long-span bridges to verify the effectiveness of the dynamic parameter correction method and the embedding process optimization scheme based on physical mechanisms, and built a reliability guarantee system that integrates equipment gradient selection, high–precision installation process, environmental interference compensation and multi-source data cross-verification, which significantly improves the confidence of monitoring data in bridge construction safety decisions.

Keywords: bridge construction monitoring; stress–strain; error traceability; data distortion; correction method

桥梁施工监控是保障施工质量与结构安全的关键环节，其核心在于准确获取结构应力应变数据，为施工决策提供科学依据，然而监测系统受多重因素影响，数据失真现象普遍存在，如未经修正直接应用于施工控制，将导致安全误判甚至工程事故。（剩余6689字）
