Effect of Plasticity Index on Liquefaction Behavior of Silty Clay
The fine-grained materials like silt or clay are of non-plastic or plastic in nature, respectively. These properties tend to make an important and consistent difference in the cyclic strength of the soil. Generally, the presence of plastic fines tends to increase the liquefaction resistance of a soil due to dilitative nature of clayey soil. But, there is a contradictive statement for non-plastic fine behavior toward liquefaction resistance. Most of the districts of Bihar falls in Seismic Zones IV and V and are highly populated. These areas have alluvial soil deposits due to existence of numerous number of flood plain. Therefore, evaluation of liquefaction susceptibility based on plasticity index of soil is necessary to provide a guide map for engineers and designers toward safe and economical design of civil engineering structures. The present paper summarizes the effect of plasticity index on liquefaction for River Ganges alluvial soil deposit area. This area is significant in terms of economy and population and falls under seismic Zone IV. Therefore, liquefaction potential analysis has also been carried out to determine the uncertainties in liquefaction resistance considering plasticity index criteria of soil deposits.
