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

In order to study how the floor stiffnesses influence on the mega steel - frame structures, the results of mode 1 and mode 4 of example 1, and those of mode 2 and mode 3 of three examples are compared. some conclusions are obtained as follows : compared with beams and columns of the common steel - frame structures, the cross - sectional dimension of mega beams and mega columns in the main - frames of mega steel - frame structures are very large. because the mega structure system has great lateral stiffness and entirety work behavior, whether or not considering the floor stiffness has less influence on the entirety responses of the mega steel - frame structures and on the displacement and internal forces of columns of the mainframe, but larger influence on the response of columns of hypo - frame
