Background

The phenomenon of liquefaction of aeolian sand along the railway line means that sandy soil or silty soil tends to be dense, so that the pore water pressure is increased rapidly, and the rapidly increased pore water pressure cannot be dissipated in time, so that the effective stress is reduced. When the effective stress is completely eliminated, the sand particles are partially or completely in a suspension state, at the moment, the shear strength of the soil body is equal to zero, and a liquid phenomenon is formed, so that the foundation beside the rail is not stable enough, and the rail is threatened greatly.

In order to eliminate the liquefaction of wind-deposited sand along the railway and avoid the threat to the rail, a ballast earthing reinforcement device is generally adopted to ballast earthing the foundation which generates the liquefaction beside the rail.
