The state-of-art of soil mechanics is briefly discussed;and it is shown that the soil mechanics is still built on the semi-theoretical and semi-empirical foundation.Then some problems with numerical method applications to geotechnical engineering are presented;and how to apply numerical methods to practice is discussed;finally

some measures to deal with the problems are given.From above discussions

some conclusions can be drawn as follows: that soil mechanics is in the infancy of state

and with the development of it and the accumulation of experience on applying soil mechanics and numerical method to practice;numerical methods in geotechnique will be applied to practice more and more;and it will become a powerful tool to deal with geotechnical problems.
