Design Method for GRS Integral Bridge with the Use of PCT Girder

抄録

Geosynthetic-Reinforced Soil (GRS) integral bridge is a bridge that rigidly joins a girder and a reinforced soil abutment. This paper describes an outline of our new joint structure connecting a prestressed concrete T-shaped (PCT) girder and an abutment, which has been an important issue in developing GRS integral bridges using PCT girders. In addition to a design method for this joint structure of a PCT girder and an abutment, unique points of a design method for GRS integral bridge with use of PCT girders are introduced.
