When the Ground Moves
The soil beneath human feet is not generally expected to move but, occasionally it does. There are several reasons that the soil moves, from the enormous liquefaction capacity of an earthquake to the sudden displacement of soil over an air pocket that may exist in a construction zone. Soil can unexpectedly shift and has the capacity to alter or even destroy objects which may be built or located on its surface. Regardless of the cause, the technology now exists to correct the subsurface profile that could result in ground failure and consequently the failure of structures above.
Soil Compaction Can Improve the Ground Beneath
Deep soil compaction is a geotechnical application of vibration of the soil at levels to better than one hundred feet below the surface. This massively applied vibration allows for the densification of the grains of soil by sifting the air pockets that exist around each of the granular components of the substrate. As the ground is vibrated, and becomes denser, the ground's ability to shift and displace diminishes.
Deep soil compaction techniques can also allow for the introduction of soil strengthening columns of stone, lime or concrete. This process can provide for construction of buildings and other structures upon soil with increased foundational load-bearing support strength.
Earthquake Caused Lakes of Mud
Liquefaction is a phenomenon that exists in certain earthquake prone parts of the world. Liquefaction is the making liquid of an otherwise solid soil structure. Solid soil structure is compromised and becomes a muddy ooze when the high volume movement of an earthquake displaces water rather than air that surrounds the soil granules in the substrate. Soil that was once solid but liquefies in an earthquake has the capacity to swallow buildings, roadways, cars and nearly anything else that is setting atop the soil prior to the event.
Studies and experiments have demonstrated the effectiveness of applying compaction of the soil in areas prone to this type of devastation. Once the deep soil of an area has been compacted mechanically, the soil becomes far denser, and the action of earthquakes has been shown to have very little further impact upon the soil which remains, for the most part, solid.
Deep soil compaction of these areas has far reaching benefits. Construction in zones prone to liquefaction during earthquakes can take place with relative assurance that the ground, once compacted, will no longer turn into a muddy ooze capable of swallowing entire buildings.
A Bright Future for Compaction
The technology for improving the ground at the substrate level for safer, refined construction, can be applied to the critical construction of retaining walls, dams, roadways and development of areas once thought to be impossible to bear structural loads. The technology is evolving and improvements are making compaction a standard in the engineering and construction industries where soil structure is known to be capable of failure. Ground improvement that is the result of compaction already benefits today's industry and has the capacity to change the way development and planning are carried out in the future .
