Abstract
This paper applies international general large-scale finite element software ANSYS to establish the finite element model of pile-soil interaction, with a project example, the influence factors for vertical bearing capacity of large-diameter belled concrete piles are analyzed. Through comparing the simulated results with field test results, it gets the results of finite is close to the measured value; and then different pile length, belled diameter and belled height influence on the vertical bearing capacity are simulated and analyzed by the finite element method. The results show that the belled diameter is larger, the vertical bearing capacity is higher, the growth is slower when D/d is greater than 2; the belled height is larger, the vertical bearing capacity 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.关键词
