There are basically three possibilities to reduce
liquefaction hazards when designing and constructing new buildings or other
structures as bridges, tunnels, and roads.
Avoid Liquefaction Susceptible Soils
The first possibility, is to avoid construction
on liquefaction susceptible soils. There are various criteria to determine the liquefaction susceptibility of a soil.
By characterizing the soil at a particular building site according to these criteria one
can decide if the site is susceptible to liquefaction and therefore unsuitable for the
desired structure. Learn more about
Build Liquefaction Resistant Structures
If it is necessary to construct on
liquefaction susceptible soil because of space restrictions, favorable location, or other
reasons, it may be possible to make the structure liquefaction resistant by designing
the foundation elements to resist the effects of liquefaction. Learn more about
design of liquefaction
Improve the Soil
The third option involves mitigation of the liquefaction
hazards by improving the strength, density, and/or drainage characteristics of the soil.
This can be done using a variety of soil improvement techniques. Learn more about
