Little information has been gathered on ground
improvement near existing lifelines. Five low vibration
ground improvement techniques suitable for remedial work
near existing structures are discussed. The five
techniques are: compaction grouting, permeation
grouting, jet grouting, in situ soil mixing, and drain
pile. Cost estimates are given for each technique,
except the drain pile technique which is not yet
available in the United States. Two reported case
histories of ground improvement near buried pipes and
conduits are reviewed. A combination of techniques may
provide a cost-effective solution for preventing damage
to existing lifelines resulting from
liquefaction-induced horizontal ground displacement,
subsidence, and uplift.
