Method for evaluating anti-overturning capability of ballastless track gravity type road shoulder retaining wall under rock foundation

The invention discloses a method for evaluating the anti-overturning capacity of a ballastless track gravity type road shoulder retaining wall under a rock foundation. The method comprises the following steps: S1, obtaining supporting embankment parameters of the gravity type retaining wall; s2, calculating an anti-overturning stability coefficient of the retaining wall; s3, calculating an anti-overturning stability coefficient limit value of the retaining wall; and S4, comparing the anti-overturning stability coefficient of the retaining wall with the anti-overturning stability coefficient limit value, and evaluating the anti-overturning capability of the retaining wall. According to the method, ballastless track subgrade surface dynamic deformation under the gravity type shoulder retaining wall supporting condition can be controlled easily, the train running state is improved, long-term stability of the subgrade under the train load effect is guaranteed, the related retaining wall anti-overturning stability
