“…After liquefaction, if the static shear stress caused by sloping ground is more than the shear strength of liquefiable soil, the non-liquefiable surface crust overlying a liquefied soil layer can slide with a considerable amount of displacement. In this condition (lateral spreading), the nonliquefiable surface layer was carried along with the underlying fully liquefiable soil and a large lateral force was imposed on the embedded piles (Ashour and Ardalan, 2011). This force due to the lateral movement of the non-liquefiable layer has the potential to induce large bending moments in the piles leading to failure.…”

a b s t r a c tLiquefaction has been a main cause of damage to civil engineering structures in seismically active areas. The effects of damage of liquefaction on deep foundations are very destructive. Seismic behavior of pile foundations is widely discussed by many researchers for safer and more economic design purposes. This paper presents a pseudo-static method for analysis of piles in liquefiable soil under seismic loads. A freefield site response analysis using three-dimensional (3D) numerical modeling was performed to determine kinematic loads from lateral ground displacements and inertial loads from vibration of the superstructure. The effects of various parameters, such as soil layering, kinematic and inertial forces, boundary condition of pile head and ground slope, on pile response were studied. By comparing the numerical results with the centrifuge test results, it can be concluded that the use of the p-y curves with various degradation factors in liquefiable sand gives reasonable results.

“…With increasing infrastructure growth and increasing earthquake activities researchers are giving more importance on this problem. Several researches were conducted by various researchers on the analysis and the design of pile foundations in liquefied soil 117 and established different theories on this behalf (Ashour et al, 2011). Codes of practices available in other countries suggest some procedure for seismic design of pile foundations also (Ghosh et al, 2012).…”

In India piles are designed as per IS 2911:2010 (Part 1) for different soil conditions considering all the load criteria. But there is no such provision in Indian Standard Codes for designing piles in potentially liquefiable soils. In this paper, the design of pile foundation in liquefiable soil is discussed. The provisions for design of pile foundations in liquefiable soil from different codes of practice from different countries are studied and the design approaches for the same are discussed based on those studies (Puri et al. 2008). The load bearing capacity of a pile in liquefied soil and non-liquefied soil is made based on the force equilibrium approach. A standardize graph which may be useful for practicing engineers has been plotted. Further, a comparative study is made based on the force equilibrium approach in Indian conditions.
