The active ground consolidator is a new energy-dissipating & shore-protecting structure,which is for the first time applied to the 12.5 m deepwater channel of the Yangtze River below Nanjing city.This paper analyzes the on-site assembly of the active ground consolidators,compares the installing efficiency by machine and by man,and concludes with the effect of scour-preventing,depositing-promoting,dune-consolidating,foreshore-protecting as well as ecological conservation of active ground consolidators.
