| Abstract: | The aim is to illustrate the method to inspect and evaluate the curved railway settlement. The embankment settlement of Shanghai-Nanjing Railway k55+450?k55+500, which is a curve section, is investigated with the dynamic penetration test and soil test. The strength of Shanghai-Nanjing railway k55+450?k55+500 track bed was calculated based on the test results; and compared it with the stress in the track bed; the strength condition of the section railway was evaluated; the mechanism of the curved railway embankment settlement is analyzed. |
