This paper applies intemational general large-scale finite element sotware ANSYS to establish thefinite element model of pile-soil interaction, with a project example, the influence factors for vertical bearingcapacity of large-diameter belled conerete piles are analyzed. Through comparing the simulated results withfield test results, it gets the results of finite is close to the measured value; and then different pile length.belled diameter and belled height influenee on the vertical bearing capacity are simulated and analyzed by thefinite element method. The results show that the belled diameter is larger, the vertical bearing capacity ishigher, the growth is slower when D/d is greater than 2; the belled height is larger, the vertical bearing ca-pacity is higher, but the growth is slow; the length of pile is longer, the vertical bearing capacity is higher,but the growth is slower when the length increase to a certain degree.
