Abstract
In the present study, the response of the pile foundation subject to seismic load in both non-liquefied and liquefied soil is investigated by developing a mathematical code. Further, the response of pile foundation is compared for both the cases of soils. It is observed from the results that the responses of pile foundation are different in both cases. It is also observed from pile response that pile embedded in liquefiable soil warrants more attention. Therefore, the evaluation of the liquefaction potential of soil is very much essential before planning of construction of any important facility or structure. Hence, in the present study, a mathematical code is also developed to evaluate the liquefaction potential of soils. A parametric study is also carried out for pile foundation in liquefied soils using developed code. During an evaluation of liquefaction potential of soil at any depth using the methods available in the literature, the amax (maximum acceleration) at ground level is used. In the present study, a method is also proposed to evaluate the liquefaction potential of soil considering the actual acceleration of soil at the depth of concern and including the soil properties, site parameters that are responsible for soil acceleration amplification.
