Bearing characteristic experiment of inclined load of soil retaining pile and numerical analysis
In order to investigate the ultimate bearing capacity of soil retaining pile under the inclined pull-up load at different angles,the load-top displacement curve of the pile was obtained through the indoor similar simulation test.Based on the consistency between the experimental parameters and the numerical simulation results of the FLAC 3D software,the influence of the load inclination on the ul-timate bearing capacity of the soil retaining pile,the distribution of the pile side friction resistance,the load-transferring behavior and the characteristics of the pile side friction resistance were further discussed.The results indicate that the load-top displacement curve of soil retaining pile presents a steep type,and the increase in the ultimate bearing capacity decreases with the fall of the inclination of the load.Due to the existence of the pile side friction resistance,the component of the pull-up load in-creases with the rise of the component of the horizontal force under the inclined load.The ultimate bearing capacity of soil retaining pile increases vastly compared with that of the constant section pile under the action of different load inclinations.The research results have a specific reference value for the design and calculation of soil retaining pile,which can be applied to engineering practice.
