The Research of Earth Pressure behind the Abutment of Integral Abutment Bridge in Uniform Temperature Difference

Abstract:

The earth pressure behind the abutment of integral abutment bridge was measured in practice. The distribution and variation laws of the earth pressure are analyzed in seasonal falling and rising temperature difference through the test data. At the same time, the mathematical model of the coefficient of passive earth pressure when temperature rising under different ratio of the superstructure deformation and the height of abutment is established. Based on the mathematical model, the calculation value of the earth pressure behind the abutment in rising temperature difference is mainly agreement with the measured value
