Article Preview

In China high-speed railway engineering practice, embankment settlements calculated values were often greatly different to the measured values, which may result from the stresses distribution under the embankment usually simplified. According to this issue, the elastic embankment method was introduced, the stresses under various embankment were calculated, the influence factors of the stresses values and distribution were analyzed. The stresses calculated by elastic embankment method, proportional load form and uniform load form were compared with the measured stresses. The relationship among the four kinds of stresses was analyzed. The applicable conditions of the various calculation methods were put forward. If the ratio of embankment half surface width and height was less than 4.5, when the stresses calculated by uniform load form were multiplied by correction coefficient 1.15, they were tallied well with the measured stresses.
