چکیده
The problems of subgrade settlement failure and uneven are quite prominent due to hydraulic migration. loess in the natural state has characteristics high strength low compressibility. Composite foundation method is set a certain proportion reinforcement (pile) foundation, so that pile soil jointly bear load, effect compaction displacement method. Based on actual case highway disease Shanxi Province, this paper studies influence treatment measures rotary jet grouting penetrating or not region by means field investigation, analysis numerical calculation. results found lateral friction resistance rotary-jet penetrates through small. When rotarjet long underlying soft layer relatively thick (4.5 m), also quickly enters stable state. deep, increases with time.

New Analytic Method for Subgrade Settlement Calculation of the New Cement Fly-ash Grave Pile-slab Structure
At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...
