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
