In order to investigate the effect of twin pile group loadings on nearby existing railway subgrade, elastic plastic model was established by adopting finite differential method based on a practical case. It is proved by comparison with field monitoring data that the numerical analysis of the influence due to twin pile group loadings on neighboring railway subgrade is reliable. The results indicate that both horizontal displacement and settlement of subgrade decrease with the increase of pile length, but both of them are insignificantly affected. Owing to superposition effect of twin pile group loading located symmetrically on both sides of subgrade, uneven additional settlement of subgrade can be mitigated, while the maximum vertical deformation is more pronounced.
