Abstract

Abstract

The embankment behind the abutment of a high-speed railway is different in the aspects of padding, construction control and quality supervision from the general railway.However,there is a little experimental research on the earth pressure behind abutment,and there are lots of factors to influence the earth pressure also,and the distribution of the earth pressure is not exact predicted through actual earth pressure theories.Therefore,a long-time site observation should be done.Based on the experiment results,the changing of the earth pressure with time and the height of embankment,the magnitude and distribution of earth pressures behind the abutment are analyzed.Test results show that the earth pressure behind abutment is nonlinearly following the depth of abutment.To begin with,the earth pressure of abutment is increased with the depth of abutment,yet after reaching a certain depth it decreased with the increase in depth abutment.The comparison is made between the results by formula and those with the experimental observations,the points of application of the resultant earth pressures have significant difference,the height of actual point of resultant earth pressure is 0.41 times of the embankment height.
