| Abstract: | According to a project in Xi'an, vertical static bearing tests and axial force tests of two bored piles with post-grouting technology have been carried out. And then axial force transfer law , working trait of side resistance and tip resistance of post-grouting piles in loess foundation are analyzed. Finally the effect of post-grouting technology on bearing capacity of bored piles is discussed. |
