| Abstract: | A research technique about the relation between soil pressure and displacement is given.In the method,two relation are gained.One relation is between soil pressure and strain from tests of stress paths;the other given by theoretical analyses is between displacement and strain,then the relation between soil pressure and displacement is obtained in response to the two relations mentioned above.According to the finite element analysis of an example,the research technique is proved to be easy and practical. |
