摘　　要：依托太行一号国家风景道(陵川段)公路项目,经过实践检验GRS桥台(土工合成材料加筋土柔性桥台复合结构)作为中小型桥梁新型结构形式,达到工后墙面位移和桥头沉降均较小,具有良好的服役性能,对山西省以后类似工程起到借鉴和总结经验作用。Based on the project of Lingchuan section of Taihang No. 1 national scenic road, the GRS abutment, the geosynthetics reinforced flexible abutment composite structure, was tested through practices. As a new type of small and medium-sized bridge structure, the GRS abutment can realize the small wall displacement and small bridge head settlement after the construction, and it has great service performance. This paper provides reference and experience for similar engineering in Shanxi.
