With reference to the engineering practices in Qing ~ Rong intercity railway, this paper introduces the general conditions of the line subgrade, the landform, the formation lithologic and the analysis of ground settlement in passing through fault zone. The requirements are proposed for subgrade deformation in non-earthquake situation to ensure safe train operation on ballasted track by widening subgrade, easing slope, reinforcing the subgrade with flexible bars, improving drainage and deformation monitoring to make the subgrade in fault zone adaptable to the deformation, easy to be maintained with reservations for future maintenance. Thus, risk is reduced and investment is saved. projects.
