The invention discloses a calculation and verification method and device for GRS bridge abutment earthquake active soil pressure, and the method specifically comprises the steps: determining GRS bridge abutment design parameters and an expected horizontal earthquake acceleration; the GRS bridge abutment design parameters comprise bridge abutment design size, wall back filling mechanical parameters, rib material distribution information and rib material parameters, bridge seat size and position, upper load distribution and the like; according to the GRS bridge abutment design parameters and the horizontal seismic acceleration, the magnitude of the seismic active earth pressure of the GRS bridge abutment is obtained through calculation; and comparing the earthquake active soil pressure of the GRS bridge abutment with the earthquake active soil pressure threshold value to determine an earthquake active soil pressure verification result of the GRS bridge abutment so as to verify the reliability of parameters in t
