In view of bearing capacity of the elastoplastic theory analysis, the author made a comparison between the achieved bearing capacity limit load pi / 4 of round base ( space problem ) and the limit load pi / 4 of bar groundwork foundation design ( plane problem ) from soil mechanics at home and abroad as well as foundation criterion, and explained why the value of formula in present design criterion from soil mechanics is inclined to be conservative. in the light of the author ' s many years experience of vibration test on the spot and the research work of relevant projects, the author worked over the dynamic pile testing of the bearing capacity of foundation and batholith, and gathered the parameter of dynamic analysis and testing. the author also talked over the difficult point of pile foundation design criteria in present batholith engineering world, i. e. the confirmation of batholith bearing capacity of pile end, from the following aspects : a ) confirmation of single axis counter - pressure strength of rock in house ; b ) f. e. m calculation of elastoplastic model ; c ) calculation of soil mechanics ; d ) deep well load test

Then, by using the great fem programme and the drucker - prager model, the thesis establishes the pile - soil model of super - long piles, analyzes the mechanism of bearing and deformation of super - long piles under vertical loading systemically, studies the characteristics of q - s curve, bottom resistance, pile shaft resistance and critical length of super - long piles in detail, acquires some practical guidance conclusion. secondly, with a practical engineering, the author expatiates the bearing characters of super - long piles farther. the thesis points that super - long piles are frictional piles under the condition of working loading
