Abstract

Abstract

Based on the theory of Particle Flow Code in 2 Dimensions(PFC~(2D)),a pile with expanded diameter that is compressed is studied,and is compared with the results of actual pile tests.Using PFC~(2D),the time step-displacement curve,the change of particle position and the displacement of particles are studied.Through the comparison of micro-mechanical properties of pile and soil during loading,the failure behavior of pile whose ultimate load is reached is also obtained.The relations between load and displacement are simulated and compared with the results of actual pile tests.
