Investigation of Ground Heave due to Jet Grouting in Soft Clay
AbstractVertical jet grouted columns by drilling holes through the embankment of busy highways are applied to mitigate the problem of excessive postconstruction settlement on the east coast of China. Short-term ground heave due to vertical jet grouted columns is focused, investigated, and analyzed via field monitoring of a construction project in Lianyungang, China. Field results show that heaves in ground surfaces were observed to be 219 mm at most. Theoretical analysis by cavity expansion was performed to investigate the soil displacement due to vertical jet grouted columns. It was found that ground surface heave decreased with smaller grout pressure, larger geostatic pressure, and a larger distance from the column center. Comparison between measured and analytical results indicated the predictability of the theoretical solution.
