ABSTRACT
Balanced cantilever method is one of the bridge construction methods, has the advantage that construction can be carried out regardless of the environment under the girder. In this method, it is important to measure the deformation of the bridge at each event such as concrete placement, tensioning, temperature change, and solar radiation. Currently, these deformations are measured by level surveying. However, level surveying for each event is time-consuming and labor-intensive, making it a challenge to improve efficiency and reduce manpower. In this study, temperature, strain, inclination, and position data were measured on PC bridges under construction as a basic study of bridge deformation measurement, and the data were analyzed in detail.
