Abstract: The classical Poulos’s elastic theory is only suitable for the behavior analysis of piles subjected to lateral soil movement in homogenous soil. But it cannot take the layered soil into account. Therefore, to satisfy the characteristics of layer soil, Poulos’s method is modified by using the Mindin’s solution considering a horizontal concentrated force, and also considering the stress &displacement solution under the ground vertical load in sandwich ground, which can be used to study the movement and internal force response of passive pile due to surcharge loading. A calculation case indicates that the modified method is more strict and reasonable than that of Poulos, with a higher calculation precision. The approach proposed can be used extensively.

Key words: Poulos’s elastic theory, sandwich ground, Mindlin’s solution, passive pile
