Development of Demonstration Equipment for the Phenomenon of Soil Liquefaction (Dr Ganesh S Kame, Professor, Department of Civil Engineering)Introduction Liquefactions and associated ground failures have been widely observed during numerous devastating earthquakes. Liquefaction occurs generally due to rapid loading during seismic events where there is not sufficient time for dissipation of excess pore-water pressures through natural drainage. Rapid loading situation increases pore-water pressures resulting in cyclic softening in fine-grained materials. The increased pore water pressure transforms granular materials from a solid to a liquefied state. Shear strength and stiffness of the soil deposit are reduced due to increase in pore water pressure. Liquefaction is observed in loose, saturated, silty sands. The soil liquefaction depends on the magnitude of earthquake, intensity and duration of ground motion, the distance from the source of the earthquake, site specific conditions, ground acceleration, type of soil and thickness of the soil deposit, relative density, grain size distribution, fines content, plasticity of fines, degree of saturation, confining pressure, permeability characteristics of soil layer, position and fluctuations of the groundwater table, reduction of effective stress, and shear modulus degradation. Liquefaction-induced ground failure is influenced by the thickness of non-liquefied and liquefied soil layers. Measures to mitigate the damages caused by liquefaction require accurate evaluation of liquefaction potential of soils. Mumbai is fifth most densely populated city in the world. Seismic soil liquefaction can be evaluated for Mumbai city in terms of the factors of safety against liquefaction (FS) along the depths of soil profiles for different earthquakes. using standard penetration test (SPT)- based simplified empirical procedure. This liquefaction potential can be evaluated at representative sites in the city using the borehole records from standard penetration tests. As the majority of the sites in the Mumbai city are of reclaimed land, the chances of liquefaction is observed to be very high at many places.

Internal Research Grant (04/02/2013)Considering importance of soil liquefaction in Mumbai city, initially it was decided to develop a demonstration equipment in the Geotechnical laboratory to bring awareness in students. Therefore, the development of working model of the equipment said above was started. Since liquefaction is a complex natural phenomenon that occurs when the upward flow of water through a cohesionless soils eliminates the shear strength. The use of liquefaction/quicksand as a convenient plot device in television and movies often leads to misconceptions, even among students taking introductory geotechnical engineering courses. Because quicksand is a familiar natural phenomenon, exploring the underlying mechanisms provides an exceptional opportunity for student learning. Studying quicksand can be facilitated by an easily constructed experimental apparatus and illustrative exercises, the construction of which is also reported ahead.Initial scheme

With this motive I applied for the Mumbai University research grant for the year 2014-2015 and got an amount of Rupees 40000/- sanctioned for this project, which was second highest.Demonstration of new model during Indian Institute of Technology Bombay, AAKAAR 2015.

During AAKAAR 2015, Indian Institute of Technology BombayAakaar was a two day Technical festival of the Department of Civil Engineering IIT Bombay in its 7th edition held during 14th - 15th March 2015. Team of our four students namely, Abhijeet Ashok Londhe, Manavendra Niranjan Mulye, Murtaza Abdulkader Khandwawala, Paras Pawan Khaitan presented their work on soil liquefaction along with researchers from all over India.
