摘要： 承重式加筋土一体化无缝桥台相较传统桥台具有桥梁减锥坡跨、避免桥头跳车、取消伸缩缝、快速建造和低碳减排的优势，在当前绿色公路、快速施工、品质工程大背景下有非常好的应用和推广价值。结合无岳高速加筋土一体化无缝桥试验工程的监测实践，详细介绍了试验工程的监测目的、内容和监测元器件的选择，总结了现场监测实施情况和注意事项。现场监测对承重式加筋土一体化无缝桥台服役机理研究及性能验证具有重要意义，也为类似工程的监测方案制定和实施提供了借鉴。

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.

Key words: GRS-IBS, Load Bearing, Jointless Bridge, Monitoring Measurement
