| Abstract: | Through the method of loading test,the change of shaft resistance and relative displacement between pile and soil under different rest time in different part of precast pile in saturated soft soil are researched from the perspective of load transfer.Time-effect on bearing capacity of friction pile is analyzed in substance. |
| |
| Keywords: | load transfer ultimate shaft resistance bearing capacity time-effect |
