Abstract:
To verify the accuracy and reliability of the pile length and parameter adopted by primary design, the axial bearing capacity and settlement of super-long pile were calculated. The displacement of pile cap and load or time, resistance of pile bottom and ultimate bearing capacity of pile were measured, the results were compared to the calculating results. The research results show that: the error of the settlement between the theoretical calculation and practice is 6.31%, two sets of data are consistent with the bored piles process and load data reasonable; bearing capacity of test pile is full, but it is less than that expected, which shows the ultimate load bearing capacity for actual design requirements is insufficient; the friction of pile side is resistance with the deform between pile and soil, the load of the bored pile top is loaded by the soil at beginning when it reaches a certain load value, the pile endpoint resistance come into action, the pile side friction, bottom resistance are fully in operation at limit state. 4 tabs, 3 figs, 11 refs.
