Integral bridge abutments in response to seasonal temperature changes: State of knowledge and recent advances

Autor: Hao Liu, Jie Han, Robert L. Parsons

Publikováno v: Frontiers in Built Environment, Vol 8 (2022)

Expansion and contraction of integral abutment bridges due to temperature changes force integral bridge abutments (IBAs) to move toward and away from the backfill, thus increasing horizontal earth pressures behind the abutments and inducing bending m

Mitigation of seasonal temperature change-induced problems with integral bridge abutments using EPS foam and geogrid

Autor: Hao Liu, Jie Han, Robert L. Parsons

Publikováno v: Geotextiles and Geomembranes. 49:1380-1392

Expansion of bridge girders in summer moves integral bridge abutments toward backfill, causing high lateral earth pressures behind the abutment. Some backfill material slumps downward and toward the abutment when the abutment moves away from the back
