Study On The Subgrade Diseases In Permafrost Of Da Guang Expressway

Soft soil foundation treatment technology in engineering exploration is still one of the hot issues, this thesis in xinyang borders on daguang guangshan section expressway across the region of soft soil physical and mechanical characteristics on the basis of analysis, in combination with the engineering practice of soft soil foundation treatment technology of the system.Xinyang territory for daguang guangshan section expressway engineering characteristics, based on the research results and the theoretical analysis of CFG pile and geogrid soft foundation treatment method in engineering of the reasonable application of field test, and the test results and the theoretical calculation result analysis, puts forward the scientific and reasonable construction technical parameters, and effective guidance to the project construction. Research on similar geological condition of design, construction, supervision and embankment are monitoring the guidance function, at the same time, to reduce vehicle dumpping phenomenon also has important reference value.
