The latest experimental results of rock creep were used : the third invariant of deviator stress tensor had greater effect on creep properties ; the stress threshold of lateral creep of rock was 20 % ~ 40 % less than that of axial creep of the same rock 文中應(yīng)用了課題組近期巖石流變實驗研究的結(jié)果:應(yīng)力偏量第三不變量對巖石蠕變影響顯著;巖石側(cè)向蠕變的應(yīng)力閥值比軸向蠕變應(yīng)力閥值低20 % ~ 40 % 。
According to the test results of localization and shear bands formation under the consolidated undrained plane strain compression tests on soft clay in shanghai , it was found that the deviator stress of shear band beginning to form was very close to its yield point in clay soils 摘要根據(jù)上海軟土在固結(jié)不排水平面應(yīng)變壓縮試驗條件下應(yīng)變局部化和剪切帶形成的實測研究結(jié)果,發(fā)現(xiàn)粘性土剪切帶開始形成的偏應(yīng)力為其屈服點。
