Abstract
In bridge engineering, monitoring pier offsets is crucial for ensuring both structural safety and construction quality. The total station measurement method using a reflector is widely employed, offering significant advantages in specific scenarios. During measurements, errors are influenced by various factors. Initially, misalignment causes the lateral relative error to increase before decreasing, while longitudinal relative errors fluctuate due to instrument characteristics and operational factors. Lateral movements have a more pronounced impact on these errors. Investigating the positioning layout of pier offsets holds substantial importance as it enables precise displacement monitoring, prevents accidents, aids in maintenance planning, provides valuable references for design and construction, and enhances the pier’s resistance to deflection. Controlling and correcting subsequent errors is essential to ensure the overall safety of the bridge structure.
