As one kind of railroad tracks, the slab track has already widely been applied in the high-speed railroad. In order to satisfy the high-speed railroad security and the comfortableness, the slab track's ultimate subsidence is controlled very strict during construction and operation. Examined in this paper is the roadbed subsidence rule of Wuhan-Guangzhou railway passenger special line in China. The site observation of roadbed settlement is utilized and the subsidence curve has drawn up. Goes a step further, based on the numerical calculus method and the forecast assessment, the roadbed settlement rules of the different ground reinforcement processing have been represented. It is shown that the ultimate subsidence satisfied the request of design.
