Scope

This document sets forth the basic provisions for the monitoring and measurement work of segment prefabrication and assembly bridges using the short-line method, establishes the procedures for data collection and monitoring parameter classification and sources, theoretical analysis of monitoring, control during the segment prefabrication phase, control during the segment assembly phase, monitoring tests during the segment assembly phase, data analysis and feedback control, and monitoring results and requirements.
This document is applicable to the monitoring and control work of the upper structure of bridges constructed using the segment prefabrication and assembly method of the short-line method, and provides technical guidance for construction.
Note: This document does not include the construction of prefabricated components of lower structures such as bridge piers. It covers two construction processes: segmental cantilever assembly and cross-by-cross assembly. It mainly describes key issues such as control methods in different construction phases, measurement point layout, measurement point stakeout and data collection accuracy, error identification and correction methods during the construction monitoring and measurement process.
