Abstract: Compared with the traditional abutments, the GRS-IBS has the advantages of reducing the span length of the bridge superstructure, avoiding the bridge jump, no joints on the bridge, rapid construction and low carbon emission. The structure has received wider applications and promoting values under the current background of promoting green road, accelerated construction and improving the quality of engineering. Based on the construction monitoring results of the Wuwei to Yuexi high-speed GRS-IBS abutments, this paper introduces the details of the monitoring purpose, content and selection of monitoring components of the project, and summarizes the implementation and matters for the field monitoring. The field monitoring is of great significance to the study of the working mechanism and the service performance of GRS-IBS, This paper also provides a reference for the monitoring plan design of similar projects.
