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.

通过对不同方法计算的台后土压力的对比分析，得知：在计算升温引起的整体式桥台桥梁台后土压力时，桥台背墙及台柱土的水平抗力系数计算采用m法是不适合的；桥台背墙后填土的水平抗力系数可采用Broms法计算；土对台桩及墩桩侧的水平抗力系数按p-y曲线来考虑是适合的。
