Study On Frost Heave And Thawing Settlement Of Artificial Freezing Under Shallow Overburden

The study took the shallow tunnel project of metro line6from Tanwei station toRuyifang station in Guangzhou as example. By numerical simulation, physicalsimulation experiment and actual measurement, the study made through analysis on thedevelopment regularity of freezing temperature field, artificial thawing field anddisplacement filed in shallow project.By numerical simulation and physical model test,we got the development law offreezing temperature field and artificial thawing temperature field,the deformation lawof formation and tracking grouting technical parameters. Conduct monitoring andanalysis the information construction of metro line6from Tanwei station to Ruyifangstation in Guangzhou. The results of numerical simulation and physical testing wasverified.
