摘要
Abstract
Foundation pile are widely used for the backfill soil layer.To suit the fill materials to local conditions,different bearing characteristics show compared to the natural foundation under the load condition.ABAQUS software was used to simulate a pile foundation project,which was constructed on a deep fill soil layer.The horizontal bearing characteristics of large-diameter piles in different backfill soil foundations were studied as a key point subject to the combined loads.The results showed that the combination of a vertical preload and the surrounding soil strength prevented the piles from the horizontal deformation under the horizontal load condition.The horizontal displacement depth of the pile body is greatly affected by the strength of the soil around the pile,and is less affected by the pre applied vertical load in the same soil filling layer.The backfill material around the piles had a significant impact on the maximum bending moment depth and the corresponding value of the pile body.关键词
