Liquefaction Behavior of Soil in Light of Sustainability
Seismic hazard is defined as an uncertain and disguised enemy of mankind and environment. The majority of studies have shown that presence of plastic fines tends to increase the liquefaction resistance of a soil. But, there is a contradictive statement for non-plastic fine soil behavior toward liquefaction resistance. Therefore, the present study evaluates the liquefaction potential of two district of high seismic region of Bihar having alluvial soil deposit considering plasticity or non-plasticity of soil which will provide a guide map for engineers and designers for economical and sustainable design of structures. The probabilistic seismic hazard analysis has been also carried out to determine the uncertainties in liquefaction resistance considering plasticity or non-plasticity of soil. For both district, it is found that fines content less than 6% do not affect cyclic resistance ratio whereas when fines content is greater than 6%, the resistance of soil toward liquefaction increases. Hence, evaluating the liquefaction susceptibility without considering fine content is conservative as well as uneconomical for the sustainable design of structures. This directs the saving of construction materials resulting saving of natural resources.
