Abstract
For high-speed railway subgrade settlement, there was usually a big difference between calculated and measured value. Studying the stresses distribution under embankment, giving more accurate simplified method，was a approach to improve the accuracy of calculated settlement. The stresses distribution under embankment were studied through tests on experimental embankment segment, geotechnical centrifuge model tests, and numerical analysis and calculation. Studies showed that the measured stresses distribution was curve, the stresses under the embankment centre were highest, under the vicinity of shoulder the stresses changed smoothly, the stresses was above zero at toe of the side slope.
