Through the comparative analysis of the earth pressure calculated by the different calculation methods, it is known that when the earth pressure behind the abutment of the integral abutment bridge under the action of rising temperatures is calculated, it is not proper to use the m method to calculate the resistance coefficients of the abutment back wall and column earth while the resistance coefficient of the abutment back wall earth can be calculated by the Broms method. It is proper that the resistance coefficients of the earth of the abutment and pier piles should be considered by the p-y curve.
