Abstract The vibrating immersed-tube crushed-stone pile is a kind of ground treating method developed in the recent 20 years. For the ground with saturated cohesive soil，especially for project which is not controlled by the deformation，the crushed-stone piles were adopted to treat the ground by replacement in order to enhance the overall stability of the weak cohesive soil ,aimed at to achieve the reinforcement of the ground. During construction of crushed-stone piles，the upper layer of A14 tender section on Qin-Shen dedicated passenger traffic railway line was newly-backfilled original cohesive soil. Combined with these special geologic conditions and the construction experiences in the past，the construction technology directed against such section was presented.
