Abstract

Long auger bored concrete pile is a kind of deep foundation, it has the advantage of pile foundation and other special advantages. Considering the particularity of the geological conditions in the loess area, study on the bearing characteristics of long spiral bored concrete pile with MIDAS/GTS software, through the numerical analysis of Long Auger Bored Cast with pressure concrete pile compared with other piles in the displacement, stress variation, and analysis of Long Auger Bored Cast with pressure concrete compared with other type of pile pile has the advantage. The results show that the GTS is a good simulation of the static loading test of pile, just a little bigger than the calculated value of experimental values, with the increase of pile top load, the influence of this error is more and more small;in the same pile diameter and geological conditions, long auger bored to many higher than the round bearing capacity of concrete pile.
