Soil Liquefaction

Abstract

Soil Liquefaction project provides knowledge on liquefaction of soils. Liquefaction can be defined as a process that creates a non-liquid phase to behave as per fluid dynamics. Soil liquefaction is when soil merely behaves like a liquid mass with hardly any shear strength rather than a solid mass. Liquefaction causes soil failures and, therefore, severe damages to structures supported on such grounds leading to significant economic losses. In this project liquefaction has been divided into two broad categories, these are liquefaction due to flow and liquefaction due to chemical processes in particular dispersive soils since structural failures attributed to dispersive soils have occurred in many countries worldwide as dispersive clay soils deflocculate and are rapidly eroded and carried away by water flow.

Conclusion

The proposed wave propagation model  can predict the behavior of real soils during strong earthquakes. The application of the model to two seismic events validates its ability to realistically take into account the influence of local site conditions and characteristics of the bedrock motion on seismic response. According to our experience a good soil profile with densities and ground water tables, combined with realistic base shaking, suffices for the free-field ground response analysis.
