The ground can be improved by adapting certain ground improvement techniques. Vibro-compaction increases the density of the soil by using powerful depth vibrators. Vacuum consolidation is used for improving soft soils by using a vacuum pump. Preloading method is used to remove pore water over time. Heating is used to form a crystalline or glass product by electric current. Ground freezing converts pore water to ice to increase their combined strength and make them impervious. Vibro-replacement stone columns improve the bearing capacity of soil whereas Vibro displacement method displaces the soil. Electro osmosis makes water flow through fine grained soils. Electro kinetic stabilization is the application of electro osmosis. Reinforced soil steel is used for retaining structures, sloping walls, dams etc. seismic loading is suited for construction in seismically active regions. Mechanically stabilized earth structures create a reinforced soil mass. The geo methods like Geosynthetics, Geogrid etc. are discussed. Soil nailing increases the shear strength of the in-situ soil and restrains its displacement. Micro pile gives the structural support and used for repair/replacement of existing foundations. Grouting is injection of pumpable materials to increase its rigidity. The jet grouting is quite advanced in speed as well as techniques when compared with the general grouting.

Following are the recent methods of ground improvement Techniques used for stabilization of soil:

  • Vibro Compaction
  • Vacuum Consolidation
  • Preloading of soil
  • Soil stabilization by heating or vitrification
  • Ground freezing
  • Vibro-replacement stone columns
  • Mechanically stabilized earth structures
  • Soil nailing
  • Micro-piles
  • Grouting

Risk management functions and quality improvement functions in an organization can overlap in terms of addressing patient safety. Using information from your own employer/organization's risk management plan, or that of an allied health care organization in your city or region, identify and summarize two such functions which commonly overlap in this manner. What common factors lead to the overlap? Does the structure work for the organization you selected? Why or why not?
