| description | The invention discloses a railway prestressed embankment slope stability analysis method. The method comprises the following steps: determining geometrical shape parameters of an embankment slope to be calculated, filler strength parameters of each structural layer and reinforcement parameters; calculating the self-weight of the track structure and the train load according to a conversion soil column method according to specifications; establishing a prestressed embankment mechanical model; performing soil strip division on the slip mass according to the potential slip surface of the embankment; according to an additional stress diffusion method, obtaining an additional normal load and an additional tangential load, caused by prestress, of the bottom surface of each soil strip; equivalent inter-strip force between adjacent soil strips is calculated through a simple method; calculating normal counter-force at the bottom of the soil strip and gliding force of the soil strip according to the stress of the soil s |
