Abstract: In this paper, the methods for making model piles and for consolidation of cohesive soils are introduced. By the model test of short-term static loading, cyclic loading and reloading after cycling, the influences of the magnitude, frequency, number of cycles and history of load on the behavior of pile are analyzed.Based on the data of the model test, p-y curves in different depths of pile are determined. Finally, the mode and influencing factors of lateral subgrade coefficient of cohesive soils are analyzed.
