| A specially designed model open -ended pile, which was composed of inner tube and outer tube, wry driven in the pressure chamber by two diffenent intallation methods, that is, impact -driving and vibratory driving, and static compression loading test was done for that pile. Through the measurement of bearing capacities in the separated resisting parts of open -ended pile, bearing mechanism of open-ended pile and soil plugging behaviors for different installation methods were studied. It appears that 20% out of soil plugging force of impact -driven pile was developed during driving, while the rest was developed during static compression loading and t.he magnitude of confining pressure applied to the chamber did not affect soil plugging behavior. Also. it appears that, soil plugging force of vibratory pile was not developed during driving, while it was developed weakly as about 0.5~0.7 times as that of impact pile during static compression loading. and the confining pressure of pressure rhamber had an effect on the soil plugging. In the ultimate loading condition unit soil plugging force did not approach to the failure condition. |
