For more information about Soil Liquefaction see original article about Soil Liquefaction.
The drastic and sever damaging effects of soil liquefaction will cause destruction which is unavoidable and is inevitable.
|Liquefaction allowed this sewer to float upward – 2004 chuetsu earthquake|
The buildings and structures whose foundations are on soil affected by liquefaction will experience a sudden loss of support which will result in drastic and irregular settlement of the building causing cracking of foundations and damage to the building structure itself.
If the foundation of a building have a small layer of liquefied soil underneath than such a foundation will face punching shear type failure.
- Bridges and Pile Foundations
If the structure or a bridge pier supported on pile is subjected to liquefaction as a result of earthquake than either the pile foundation will buckle or it will slightly tilt after shaking due to earthquake.
- Sloping Grounds
Slopes and grounds that are near a river or a lake may slide after liquefaction as already explained as flow liquefaction causing cracks in ground and damage to the adjacent structures.
- Utility Services
Bridges, roads and other utility services like that of power, telecommunication, sewerage and natural gas will be damaged poorly due to failure as a result of liquefaction. The manholes may rise up due to buyout force caused by water in liquefaction.
- Earth Embankments
Earth embankments, dams and other earth retaining structures after liquefaction will collapse or become unstable making it unusable and impractical.
