 note = {The three shear tests under constant volume condition were carried out to clarify the coincidence of the stress path of the undrained shear test with constant volume test to confirm the introduction of state boundary surface concept. Experimentally those three stress paths of tests were given similarly. As a result, the validity of concept of the state boundary surface was confirmed. Also, the distribution of water content in the specimen during shear were measured to make sure the effect on the shearing behavior. The distribution of internal water content had changed according as the shear progressed, showing high water content in the top and bottom region and low water content in the center of the specimen., 紀要論文},
