Archimedes principle has been applied in the present study. During a high-magnitude earthquake, the structure may not float for a long time, but may sink instead of tilting. The main aim of this study is to restrict tilting and allow the structure to float on liquefied soil. Tilting also results in loss of life and property. Once tilted, the structure is to be dismantled. Niigata earthquake resulted in tilting of a number of buildings. Tilting of foundations during liquefaction of soil is one of the primary concerns for stability of structures constructed in saturated sand in seismically active areas. This proved that densification or increasing confining pressure improves resistance against liquefaction which can be considered as the cheapest soil improvement technique to mitigate liquefaction hazards in unconstrained areas. From the results, it was also observed that higher confining pressures resulted in decrease in pore pressure whereas higher amplitude of loading resulted in a rise in pore pressure. Similarly, confining pressures of 100 and 150В kPa for amplitudes ranging from 0.08 to 1% were also considered.

Tests were carried out at relative densities, i.e., 35, 50, and 65%, and reduction in pore pressure with increase in relative density was observed.

So, in the present study, a comprehensive experimental program was undertaken in which a series of strain-controlled cyclic triaxial tests were performed to evaluate the liquefaction resistance of local sand in Warangal. The devastation brought by it due to earthquakes of Niigata (Japan), Bhuj (India), Nepal has turned the spotlight on the seriousness with which this hazard has to be considered. Also, its study became a part and parcel of seismic microzonation considering its severity. Liquefaction has become one of the most important and interesting topics in the field of geotechnical earthquake engineering.
